Hi all,
Recently, we are developing USB driver for our products, and we found the
"usb_unlink_urb" function not work.
The S/W platform is Fedora Core 2 with kernel version 2.6.5-1, when we open
our USB device node, we submit the read_urb,
and it is expected to be unlinked when the user program close USB device.
But the "usb_unlink_urb" seems blocked when close function excuting, and
released on the next time the USB device plug-in.
(when un-plug and then plug-in the device again)
Is this a bug in linux kernel under version 2.6.9 ? or something wrong in our
driver ? how could we fix this?
Thanks a lot and wish you a good day!
Regards,
oct
