Description Roberto Salomon 2005-11-25 17:41:56 UTC

Connecting a Logitech Quickcam express with driver qc-usb results in a kernel panic on SUSE Linux 10.0 (kernel 2.6.13-15-default). The problem is related to file ohci-q.c line 108. Changing the line from:

#if 1 /* CONFIG_USB_BANDWIDTH */

to

#if 0 /* CONFIG_USB_BANDWIDTH */

and recompiling the kernel resulted in the camera funcioning normally and the system once again stable.

I think this is for you Greg.

Comment 2 Greg Kroah-Hartman 2005-11-28 20:03:10 UTC

No, the bug is in the qc-usb driver, it should work with the ohci driver
either way.

Where did you get the qc-usb driver from?

Comment 3 Roberto Salomon 2005-11-29 10:10:54 UTC

The driver was downloaded from qce-ga.sourceforge.net. The only way to have the camera working with the default kernel on SUSE 10.0 was to change the ohci bandwidth configuration.

Comment 4 Greg Kroah-Hartman 2005-11-29 19:33:51 UTC

As you downloaded the driver from some external place, I suggest you contact
those developers as to what the problem is with their driver (no in-kernel driver
needs this kind of ohci change.)

There's nothing we can really do about this, sorry.
