People sometimes create their own custom-configured kernels and forget to enable CONFIG_SCSI_MULTI_LUN. This causes problems when they plug in a USB storage device (such as a card reader) with more than one LUN. Fortunately, we can tell fairly easily when a storage device claims to have more than one LUN. When that happens, this patch asks the SCSI layer to probe all the LUNs automatically, regardless of the config setting. The patch also updates the Kconfig help text for usb-storage, explaining that CONFIG_SCSI_MULTI_LUN may be necessary.

---help---
|
|
Say Y here if you want to connect USB mass storage devices to your
|
|
computer's USB port. This is the driver you need for USB
|
|
floppy drives, USB hard disks, USB tape drives, USB CD-ROMs,
|
|
USB flash devices, and memory sticks, along with
|
|
similar devices. This driver may also be used for some cameras
|
|
and card readers.
|
|
|
|
This option depends on 'SCSI' support being enabled, but you
|
|
probably also need 'SCSI device support: SCSI disk support'
|
|
(BLK_DEV_SD) for most USB storage devices. Some devices also
|
|
will require 'Probe all LUNs on each SCSI device'
|
|
(SCSI_MULTI_LUN).

module will be called usb-storage.
