* This driver allows a USB IrDA device to be used as a "dumb" serial device.
|
|
|
|
* This can be useful if you do not have access to a full IrDA stack on the
|
|
|
|
* other side of the connection. If you do have an IrDA stack on both devices,
|
|
|
|
* please use the usb-irda driver, as it contains the proper error checking and
|
|
|
|
* other goodness of a full IrDA stack.
|
|
|
|
*
|
|
|
|
* Portions of this driver were taken from drivers/net/irda/irda-usb.c, which
