Thank you for your answer,
I think i miswrote the problem. I used urb->next = urb to continuosly submit an
URB. Under certain conditions, i need to remove any other submitions from within the
completition handler (and exit from it). But the kernel suddenly crashes. I am using
Linux 2.4.19 and the uhci module. I am sure the unlink function is the cause of the
problem.
