hi, thanks for all the replies.
-i call wait_for_completion() from my read/write entry points -in URB's completion handler, call complete() -when cancellation needed, call usb_unlink_urb() -the URB's completion handler gets called with err code on cancellation -thus, cancellation also uses the same strategy hope this will work fine.. thanks, prageeth --- Oliver Neukum <[EMAIL PROTECTED]> wrote: > Am Freitag, 8.
