Subject: [PATCH] USB: trancevibrator: fix control-request direction
Date: Fri, 21 May 2021 15:31:09 +0200 [thread overview]
Message-ID: <20210521133109.17396-1-johan@kernel.org> (raw)
The direction of the pipe argument must match the request-type direction
bit or control requests may fail depending on the host-controller-driver
implementation.
Fix the set-speed request which erroneously used USB_DIR_IN and update
the default timeout argument to match (same value).
Fixes: 5638e4d92e77 ("USB: add PlayStation 2 Trance Vibrator driver")
Cc: stable@vger.kernel.org # 2.6.19
