This patch removes the auerswald USB driver from the linux kernel 2.6.26. This driver was included into the kernel mainly to connect to the ISDN framework. This was done in linux 2.4.x. For 2.6.x, due to the fragile and moving ISDN support, this connection was never realized, and the only use of this driver was for device configuration. In the age of DSL, the demand of ISDN support is getting very low. Meanwhile, with the advent of libusb, an userspace driver was done for the device configuration which works fine for linux and mac. (Thanks to the libusb developers!). The userspace driver is downloadable from the auerswald web site. So this driver is obsolete now and has to be removed. Many thanks to all developers which helped me to bring this driver up and working. Signed-off-by: Wolfgang Muees <wolfgang@iksw-muees.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

LINUX ALLOCATED DEVICES (2.6+ version)
|
|
|
|
Maintained by Torben Mathiasen <device@lanana.org>
|
|
|
|
Last revised: 29 November 2006

|
|
|
This list is the Linux Device List, the official registry of allocated
|
|
device numbers and /dev directory nodes for the Linux operating
|
|
system.
|
|
|
|
The latest version of this list is available from
|
|
http://www.lanana.org/docs/device-list/ or
|
|
ftp://ftp.kernel.org/pub/linux/docs/device-list/. This version may be
|
|
newer than the one distributed with the Linux kernel.
|
|
|
|
The LaTeX version of this document is no longer maintained.
|
|
|
|
This document is included by reference into the Filesystem Hierarchy
|
|
Standard (FHS). The FHS is available from http://www.pathname.com/fhs/.
|
|
|
|
Allocations marked (68k/Amiga) apply to Linux/68k on the Amiga
|
|
platform only. Allocations marked (68k/Atari) apply to Linux/68k on
|
|
the Atari platform only.
|
|
|
|
The symbol {2.6} means the allocation is obsolete and scheduled for
|
|
removal once kernel version 2.6 (or equivalent) is released. Some of these
|
|
allocations have already been removed.
|
|
|
|
This document is in the public domain. The author requests, however,
|
|
that semantically altered versions are not distributed without
|
|
permission of the author, assuming the author can be contacted without
|
|
an unreasonable effort.
|
|
|
|
In particular, please don't sent patches for this list to Linus, at
|
|
least not without contacting me first.
|
|
|
|
I do not have any information about these devices beyond what appears
|
|
on this list. Any such information requests will be deleted without
|
|
reply.
|
|
|
|
|
|
**** DEVICE DRIVERS AUTHORS PLEASE READ THIS ****
|
|
|
|
To have a major number allocated, or a minor number in situations
|
|
where that applies (e.g. busmice), please contact me with the
|
|
appropriate device information. Also, if you have additional
|
|
information regarding any of the devices listed below, or if I have
|
|
made a mistake, I would greatly appreciate a note.
|
|
|
|
I do, however, make a few requests about the nature of your report.
|
|
This is necessary for me to be able to keep this list up to date and
|
|
correct in a timely manner. First of all, *please* send it to the
|
|
correct address... <device@lanana.org>. I receive hundreds of email
|
|
messages a day, so mail sent to other addresses may very well get lost
|
|
in the avalanche. Please put in a descriptive subject, so I can find
|
|
your mail again should I need to. Too many people send me email
|
|
saying just "device number request" in the subject.
|
|
|
|
Second, please include a description of the device *in the same format
|
|
as this list*. The reason for this is that it is the only way I have
|
|
found to ensure I have all the requisite information to publish your
|
|
device and avoid conflicts.
|
|
|
|
Third, please don't assume that the distributed version of the list is
|
|
up to date. Due to the number of registrations I have to maintain it
|
|
in "batch mode", so there is likely additional registrations that
|
|
haven't been listed yet.
|
|
|
|
Finally, sometimes I have to play "namespace police." Please don't be
|
|
offended. I often get submissions for /dev names that would be bound
|
|
to cause conflicts down the road. I am trying to avoid getting in a
|
|
situation where we would have to suffer an incompatible forward
|
|
change. Therefore, please consult with me *before* you make your
|
|
device names and numbers in any way public, at least to the point
|
|
where it would be at all difficult to get them changed.
|
|
|
|
Your cooperation is appreciated.

0 Unnamed devices (e.g. non-device mounts)
|
|
0 = reserved as null device number
|
|
See block major 144, 145, 146 for expansion areas.

|
|
1 char Memory devices
|
|
1 = /dev/mem Physical memory access
|
|
2 = /dev/kmem Kernel virtual memory access
|
|
3 = /dev/null Null device
|
|
4 = /dev/port I/O port access
|
|
5 = /dev/zero Null byte source
|
|
6 = /dev/core OBSOLETE - replaced by /proc/kcore
|
|
7 = /dev/full Returns ENOSPC on write
|
|
8 = /dev/random Nondeterministic random number gen.
|
|
9 = /dev/urandom Faster, less secure random number gen.
|
|
10 = /dev/aio Asynchronous I/O notification interface
|
|
11 = /dev/kmsg Writes to this come out as printk's
|
|
12 = /dev/oldmem Used by crashdump kernels to access
|
|
the memory of the kernel that crashed.
|
|
|
|
1 block RAM disk
|
|
0 = /dev/ram0 First RAM disk
|
|
1 = /dev/ram1 Second RAM disk
|
|
...
|
|
250 = /dev/initrd Initial RAM disk {2.6}
|
|
|
|
Older kernels had /dev/ramdisk (1, 1) here.
|
|
/dev/initrd refers to a RAM disk which was preloaded
|
|
by the boot loader; newer kernels use /dev/ram0 for
|
|
the initrd.
|
|
|
|
2 char Pseudo-TTY masters
|
|
0 = /dev/ptyp0 First PTY master
|
|
1 = /dev/ptyp1 Second PTY master
|
|
...
|
|
255 = /dev/ptyef 256th PTY master
|
|
|
|
Pseudo-tty's are named as follows:
|
|
* Masters are "pty", slaves are "tty";
|
|
* the fourth letter is one of pqrstuvwxyzabcde indicating
|
|
the 1st through 16th series of 16 pseudo-ttys each, and
|
|
* the fifth letter is one of 0123456789abcdef indicating
|
|
the position within the series.
|
|
|
|
These are the old-style (BSD) PTY devices; Unix98
|
|
devices are on major 128 and above and use the PTY
|
|
master multiplex (/dev/ptmx) to acquire a PTY on
|
|
demand.
|
|
|
|
2 block Floppy disks
|
|
0 = /dev/fd0 Controller 0, drive 0, autodetect

|
|
|
|
(1) Autodetectable format
|
|
(2) Autodetectable format in a Double Density (720K) drive only
|
|
(3) Autodetectable format in a High Density (1440K) drive only
|
|
|
|
NOTE: The letter in the device name (d, q, h or u)
|
|
signifies the type of drive: 5.25" Double Density (d),
|
|
5.25" Quad Density (q), 5.25" High Density (h) or 3.5"
|
|
(any model, u). The use of the capital letters D, H
|
|
and E for the 3.5" models have been deprecated, since
|
|
the drive type is insignificant for these devices.
|
|
|
|
3 char Pseudo-TTY slaves
|
|
0 = /dev/ttyp0 First PTY slave
|
|
1 = /dev/ttyp1 Second PTY slave
|
|
...
|
|
255 = /dev/ttyef 256th PTY slave
|
|
|
|
These are the old-style (BSD) PTY devices; Unix98
|
|
devices are on major 136 and above.
|
|
|
|
3 block First MFM, RLL and IDE hard disk/CD-ROM interface
|
|
0 = /dev/hda Master: whole disk (or CD-ROM)
|
|
64 = /dev/hdb Slave: whole disk (or CD-ROM)
|
|
|
|
For partitions, add to the whole disk device number:
|
|
0 = /dev/hd? Whole disk
|
|
1 = /dev/hd?1 First partition
|
|
2 = /dev/hd?2 Second partition
|
|
...
|
|
63 = /dev/hd?63 63rd partition
|
|
|
|
For Linux/i386, partitions 1-4 are the primary
|
|
partitions, and 5 and above are logical partitions.
|
|
Other versions of Linux use partitioning schemes
|
|
appropriate to their respective architectures.
|
|
|
|
4 char TTY devices
|
|
0 = /dev/tty0 Current virtual console
|
|
|
|
1 = /dev/tty1 First virtual console
|
|
...
|
|
63 = /dev/tty63 63rd virtual console
|
|
64 = /dev/ttyS0 First UART serial port
|
|
...
|
|
255 = /dev/ttyS191 192nd UART serial port
|
|
|
|
UART serial ports refer to 8250/16450/16550 series devices.
|
|
|
|
Older versions of the Linux kernel used this major
|
|
number for BSD PTY devices. As of Linux 2.1.115, this
|
|
is no longer supported. Use major numbers 2 and 3.
|
|
|
|
4 block Aliases for dynamically allocated major devices to be used
|
|
when its not possible to create the real device nodes
|
|
because the root filesystem is mounted read-only.
|
|
|
|
0 = /dev/root
|
|
|
|
5 char Alternate TTY devices
|
|
0 = /dev/tty Current TTY device
|
|
1 = /dev/console System console
|
|
2 = /dev/ptmx PTY master multiplex
|
|
64 = /dev/cua0 Callout device for ttyS0
|
|
...
|
|
255 = /dev/cua191 Callout device for ttyS191
|
|
|
|
(5,1) is /dev/console starting with Linux 2.1.71. See
|
|
the section on terminal devices for more information
|
|
on /dev/console.
|
|
|
|
6 char Parallel printer devices
|
|
0 = /dev/lp0 Parallel printer on parport0
|
|
1 = /dev/lp1 Parallel printer on parport1
|
|
...
|
|
|
|
Current Linux kernels no longer have a fixed mapping
|
|
between parallel ports and I/O addresses. Instead,
|
|
they are redirected through the parport multiplex layer.
|
|
|
|
7 char Virtual console capture devices
|
|
0 = /dev/vcs Current vc text contents
|
|
1 = /dev/vcs1 tty1 text contents
|

63 = /dev/vcs63 tty63 text contents
|
|
128 = /dev/vcsa Current vc text/attribute contents
|
|
129 = /dev/vcsa1 tty1 text/attribute contents
|
|
...
|
|
191 = /dev/vcsa63 tty63 text/attribute contents
|
|
|
|
NOTE: These devices permit both read and write access.
|
|
|
|
7 block Loopback devices
|
|
0 = /dev/loop0 First loop device
|
|
1 = /dev/loop1 Second loop device
|
|
...
|
|
|
|
The loop devices are used to mount filesystems not
|
|
associated with block devices. The binding to the
|
|
loop devices is handled by mount(8) or losetup(8).
|
|
|
|
8 block SCSI disk devices (0-15)
|
|
0 = /dev/sda First SCSI disk whole disk
|
|
16 = /dev/sdb Second SCSI disk whole disk
|
|
32 = /dev/sdc Third SCSI disk whole disk
|
|
...
|
|
240 = /dev/sdp Sixteenth SCSI disk whole disk
|
|
|
|
Partitions are handled in the same way as for IDE
|
|
disks (see major number 3) except that the limit on
|
|
partitions is 15.
|
|
|
|
9 char SCSI tape devices
|
|
0 = /dev/st0 First SCSI tape, mode 0
|
|
1 = /dev/st1 Second SCSI tape, mode 0
|
|
...
|
|
32 = /dev/st0l First SCSI tape, mode 1
|
|
33 = /dev/st1l Second SCSI tape, mode 1
|
|
...
|
|
64 = /dev/st0m First SCSI tape, mode 2
|
|
65 = /dev/st1m Second SCSI tape, mode 2
|
|
...
|
|
96 = /dev/st0a First SCSI tape, mode 3
|
|
97 = /dev/st1a Second SCSI tape, mode 3
|
|
...
|
|
128 = /dev/nst0 First SCSI tape, mode 0, no rewind
|
|
129 = /dev/nst1 Second SCSI tape, mode 0, no rewind
|
|
...
|
|
160 = /dev/nst0l First SCSI tape, mode 1, no rewind
|
|
161 = /dev/nst1l Second SCSI tape, mode 1, no rewind
|
|
...
|
|
192 = /dev/nst0m First SCSI tape, mode 2, no rewind
|
|
193 = /dev/nst1m Second SCSI tape, mode 2, no rewind
|
|
...
|
|
224 = /dev/nst0a First SCSI tape, mode 3, no rewind
|
|
225 = /dev/nst1a Second SCSI tape, mode 3, no rewind
|
|
...
|
|
|
|
"No rewind" refers to the omission of the default
|
|
automatic rewind on device close. The MTREW or MTOFFL
|
|
ioctl()'s can be used to rewind the tape regardless of
|
|
the device used to access it.
|
|
|
|
9 block Metadisk (RAID) devices
|
|
0 = /dev/md0 First metadisk group
|
|
1 = /dev/md1 Second metadisk group
|
|
...
|
|
|
|
The metadisk driver is used to span a
|
|
filesystem across multiple physical disks.

removal of a driver with this number should not cause

IN PARTICULAR, ANY DISTRIBUTION WHICH CONTAINS A
|

The OnStream SC-x0 SCSI tapes do not support the
|
|
standard SCSI SASD command set and therefore need
|
|
their own driver "osst". Note that the IDE, USB (and
|
|
maybe ParPort) versions may be driven via ide-scsi or
|
|
usb-storage SCSI emulation and this osst device and
|
|
driver as well. The ADR-x0 drives are QIC-157
|
|
compliant and don't need osst.

**** ADDITIONAL /dev DIRECTORY ENTRIES
|
|
|
|
This section details additional entries that should or may exist in
|
|
the /dev directory. It is preferred that symbolic links use the same
|
|
form (absolute or relative) as is indicated here. Links are
|
|
classified as "hard" or "symbolic" depending on the preferred type of
|
|
link; if possible, the indicated type of link should be used.
|
|
|
|
|
|
Compulsory links
|
|
|
|
These links should exist on all systems:
|
|
|
|
/dev/fd /proc/self/fd symbolic File descriptors
|
|
/dev/stdin fd/0 symbolic stdin file descriptor
|
|
/dev/stdout fd/1 symbolic stdout file descriptor
|
|
/dev/stderr fd/2 symbolic stderr file descriptor
|
|
/dev/nfsd socksys symbolic Required by iBCS-2
|
|
/dev/X0R null symbolic Required by iBCS-2
|
|
|
|
Note: /dev/X0R is <letter X>-<digit 0>-<letter R>.
|
|
|
|
Recommended links
|
|
|
|
It is recommended that these links exist on all systems:
|
|
|
|
/dev/core /proc/kcore symbolic Backward compatibility
|
|
/dev/ramdisk ram0 symbolic Backward compatibility
|
|
/dev/ftape qft0 symbolic Backward compatibility
|
|
/dev/bttv0 video0 symbolic Backward compatibility
|
|
/dev/radio radio0 symbolic Backward compatibility
|
|
/dev/i2o* /dev/i2o/* symbolic Backward compatibility
|
|
/dev/scd? sr? hard Alternate SCSI CD-ROM name
|
|
|
|
Locally defined links
|
|
|
|
The following links may be established locally to conform to the
|
|
configuration of the system. This is merely a tabulation of existing
|
|
practice, and does not constitute a recommendation. However, if they
|
|
exist, they should have the following uses.
|
|
|
|
/dev/mouse mouse port symbolic Current mouse device
|
|
/dev/tape tape device symbolic Current tape device
|
|
/dev/cdrom CD-ROM device symbolic Current CD-ROM device
|
|
/dev/cdwriter CD-writer symbolic Current CD-writer device
|
|
/dev/scanner scanner symbolic Current scanner device
|
|
/dev/modem modem port symbolic Current dialout device
|
|
/dev/root root device symbolic Current root filesystem
|
|
/dev/swap swap device symbolic Current swap device
|
|
|
|
/dev/modem should not be used for a modem which supports dialin as
|
|
well as dialout, as it tends to cause lock file problems. If it
|
|
exists, /dev/modem should point to the appropriate primary TTY device
|
|
(the use of the alternate callout devices is deprecated).
|
|
|
|
For SCSI devices, /dev/tape and /dev/cdrom should point to the
|
|
``cooked'' devices (/dev/st* and /dev/sr*, respectively), whereas
|
|
/dev/cdwriter and /dev/scanner should point to the appropriate generic
|
|
SCSI devices (/dev/sg*).
|
|
|
|
/dev/mouse may point to a primary serial TTY device, a hardware mouse
|
|
device, or a socket for a mouse driver program (e.g. /dev/gpmdata).
|
|
|
|
Sockets and pipes
|
|
|
|
Non-transient sockets and named pipes may exist in /dev. Common entries are:
|
|
|
|
/dev/printer socket lpd local socket
|
|
/dev/log socket syslog local socket
|
|
/dev/gpmdata socket gpm mouse multiplexer
|
|
|
|
Mount points
|
|
|
|
The following names are reserved for mounting special filesystems
|
|
under /dev. These special filesystems provide kernel interfaces that
|
|
cannot be provided with standard device nodes.
|
|
|
|
/dev/pts devpts PTY slave filesystem
|
|
/dev/shm tmpfs POSIX shared memory maintenance access

|
|
|
**** TERMINAL DEVICES
|
|
|
|
Terminal, or TTY devices are a special class of character devices. A
|
|
terminal device is any device that could act as a controlling terminal
|
|
for a session; this includes virtual consoles, serial ports, and
|
|
pseudoterminals (PTYs).
|
|
|
|
All terminal devices share a common set of capabilities known as line
|
|
disciplines; these include the common terminal line discipline as well
|
|
as SLIP and PPP modes.
|
|
|
|
All terminal devices are named similarly; this section explains the
|
|
naming and use of the various types of TTYs. Note that the naming
|
|
conventions include several historical warts; some of these are
|
|
Linux-specific, some were inherited from other systems, and some
|
|
reflect Linux outgrowing a borrowed convention.
|
|
|
|
A hash mark (#) in a device name is used here to indicate a decimal
|
|
number without leading zeroes.
|
|
|
|
Virtual consoles and the console device
|
|
|
|
Virtual consoles are full-screen terminal displays on the system video
|
|
monitor. Virtual consoles are named /dev/tty#, with numbering
|
|
starting at /dev/tty1; /dev/tty0 is the current virtual console.
|
|
/dev/tty0 is the device that should be used to access the system video
|
|
card on those architectures for which the frame buffer devices
|
|
(/dev/fb*) are not applicable. Do not use /dev/console
|
|
for this purpose.
|
|
|
|
The console device, /dev/console, is the device to which system
|
|
messages should be sent, and on which logins should be permitted in
|
|
single-user mode. Starting with Linux 2.1.71, /dev/console is managed
|
|
by the kernel; for previous versions it should be a symbolic link to
|
|
either /dev/tty0, a specific virtual console such as /dev/tty1, or to
|
|
a serial port primary (tty*, not cu*) device, depending on the
|
|
configuration of the system.
|
|
|
|
Serial ports
|
|
|
|
Serial ports are RS-232 serial ports and any device which simulates
|
|
one, either in hardware (such as internal modems) or in software (such
|
|
as the ISDN driver.) Under Linux, each serial ports has two device
|
|
names, the primary or callin device and the alternate or callout one.
|
|
Each kind of device is indicated by a different letter. For any
|
|
letter X, the names of the devices are /dev/ttyX# and /dev/cux#,
|
|
respectively; for historical reasons, /dev/ttyS# and /dev/ttyC#
|
|
correspond to /dev/cua# and /dev/cub#. In the future, it should be
|
|
expected that multiple letters will be used; all letters will be upper
|
|
case for the "tty" device (e.g. /dev/ttyDP#) and lower case for the
|
|
"cu" device (e.g. /dev/cudp#).
|
|
|
|
The names /dev/ttyQ# and /dev/cuq# are reserved for local use.
|
|
|
|
The alternate devices provide for kernel-based exclusion and somewhat
|
|
different defaults than the primary devices. Their main purpose is to
|
|
allow the use of serial ports with programs with no inherent or broken
|
|
support for serial ports. Their use is deprecated, and they may be
|
|
removed from a future version of Linux.
|
|
|
|
Arbitration of serial ports is provided by the use of lock files with
|
|
the names /var/lock/LCK..ttyX#. The contents of the lock file should
|
|
be the PID of the locking process as an ASCII number.
|
|
|
|
It is common practice to install links such as /dev/modem
|
|
which point to serial ports. In order to ensure proper locking in the
|
|
presence of these links, it is recommended that software chase
|
|
symlinks and lock all possible names; additionally, it is recommended
|
|
that a lock file be installed with the corresponding alternate
|
|
device. In order to avoid deadlocks, it is recommended that the locks
|
|
are acquired in the following order, and released in the reverse:
|
|
|
|
1. The symbolic link name, if any (/var/lock/LCK..modem)
|
|
2. The "tty" name (/var/lock/LCK..ttyS2)
|
|
3. The alternate device name (/var/lock/LCK..cua2)
|
|
|
|
In the case of nested symbolic links, the lock files should be
|
|
installed in the order the symlinks are resolved.
|
|
|
|
Under no circumstances should an application hold a lock while waiting
|
|
for another to be released. In addition, applications which attempt
|
|
to create lock files for the corresponding alternate device names
|
|
should take into account the possibility of being used on a non-serial
|
|
port TTY, for which no alternate device would exist.
|
|
|
|
Pseudoterminals (PTYs)
|
|
|
|
Pseudoterminals, or PTYs, are used to create login sessions or provide
|
|
other capabilities requiring a TTY line discipline (including SLIP or
|
|
PPP capability) to arbitrary data-generation processes. Each PTY has
|
|
a master side, named /dev/pty[p-za-e][0-9a-f], and a slave side, named
|
|
/dev/tty[p-za-e][0-9a-f]. The kernel arbitrates the use of PTYs by
|
|
allowing each master side to be opened only once.
|
|
|
|
Once the master side has been opened, the corresponding slave device
|
|
can be used in the same manner as any TTY device. The master and
|
|
slave devices are connected by the kernel, generating the equivalent
|
|
of a bidirectional pipe with TTY capabilities.
|
|
|
|
Recent versions of the Linux kernels and GNU libc contain support for
|
|
the System V/Unix98 naming scheme for PTYs, which assigns a common
|
|
device, /dev/ptmx, to all the masters (opening it will automatically
|
|
give you a previously unassigned PTY) and a subdirectory, /dev/pts,
|
|
for the slaves; the slaves are named with decimal integers (/dev/pts/#
|
|
in our notation). This removes the problem of exhausting the
|
|
namespace and enables the kernel to automatically create the device
|
|
nodes for the slaves on demand using the "devpts" filesystem.
