Dwaine Garden from the test mailing list wrote: https://www.redhat.com/archives/fedora-test-list/2005-January/msg00103.html It's dying on the usb_unlink_urb() I had to rewrite the code for the usbvision to fix the bombing. Look for the following.... errCode = usb_unlink_urb(usbvision->sbuf[bufIdx].urb); if (errCode < 0) err("%s: usb_unlink_urb() failed: error %d", __FUNCTION__, errCode); Change it to the usb_kill_urb usb_kill_urb(usbvision->sbuf[bufIdx].urb); usb_free_urb(usbvision->sbuf[bufIdx].urb); usbvision->sbuf[bufIdx].urb = NULL; Make sure to subsitute the usbvision to whatever is used in the pwc driver. It should fix it. Dwaine.
should be fixed in todays updates.
