In the\ncomplete callback usb_8dev_read_bulk_callback(), the URBs are processed and\nresubmitted. In usb_8dev_close() -> unlink_all_urbs() the URBs are freed by\ncalling usb_kill_anchored_urbs(&priv->rx_submitted).\n\nHowever, this does not take into account that the USB framework unanchors\nthe URB before the complete function is called. This means that once an\nin-URB has been completed, it is no longer anchored and is ultimately not\nreleased in usb_kill_anchored_urbs().\n\nFix the memory leak by anchoring the URB in the\nusb_8dev_read_bulk_callback() to the priv->rx_submitted anchor."
