[1.] One line summary of the problem:
Problems with USB (uhci_hcd) + V4L + stv680 driver

[2.] Full description of the problem/report:
The problem is quite simple: when I use UHCI_HDC + V4L + stv680
drivers and the program "Camorama" to see the video "produced" by my
Web-Cam (OREGON Scientific DS-3868) all seem to work fine...
but after some time (that is variable) the video stops on a frame!
Then If I unplug and then replug my Web-Cam I get an Oops!

Kernel config attached.
Any idea?

(PLEASE CC me, I'm not subscribed to the USB-DEVEL mailing list)
