[Bug 464429] [NEW] usb_storage lost exclusion for Huawei 220 UMTS dongle

[cdegroot]

Public bug reported:

This looks like a regression in the most recent Karmic kernel update
(2.6.31-14). The Huwai UMTS modem comes with a built in rom drive
containing the windows drivers, but this thing is messed up and useless
anyway under Linux so usb_storage should ignore it. As far as I can
tell, this was patched in 2.6.20 and the modem has been working fine
until the kernel update, where usb_storage starts probing for the
detected rom drive and fails horribly:

The kernel doesn't seem to know about resetting USB "subdevices" so the
whole dongle goes away, comes back, and the thing repeats.

Work-around is to open a terminal and rmmod usb_storage, but this is not
a long-term solution.
