From: Chris Malley <[EMAIL PROTECTED]>
The patch below is a necessary workaround to support the BT On-Air USB modem,
which
fails to initialise properly during normal probing thus:
Sep 30 17:34:57 sled kernel: drivers/usb/class/cdc-acm.c: Zero length
descriptor references
Sep 30 17:34:57 sled kernel: cdc_acm: probe of 1-1.2:1.0 failed with error -22
Adding the patch below causes the probing section to be skipped, and the modem
then initialises correctly.
