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.
