yes it should be...but I can't find out where it is. For now the only
possibility I found is the urb is not unlinked when giving back to the
driver. Or maybe in hcd->urb_dequeue I'm doing wrong things ? What I'm
doing is if the urb passed is not the active one then I simply call
usb_hcd_giveback_urb function. Oh well....
Thanks.
