Description Arne Woerner 2009-12-29 20:40:31 UTC
it seems like, some recent change to the kernel destroyed support for my usb device 2770:915d (a umass device of a usb cam)...

can u fix it?

https://bugzilla.redhat.com/show_bug.cgi?id=540105
http://bugs.gentoo.org/show_bug.cgi?id=297357

Changing the Subject line (as I did above) ought to work.

As a matter of fact, you _can_ disable it.  In your /etc/modprobe.conf, 
add a line saying

	options usb-storage quirks=2770:915d:

All USB bugs should be sent to the linux-usb@vger.kernel.org mailing 
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.
