Subject: [PATCH v3 5/5] media: uvcvideo: Force UVC version for Avermedia GC515
Date: Fri, 11 Sep 2026 13:22:29 +0000 [thread overview]
Message-ID: <20260911-uvc-version-v3-5-604328d8a0dd@chromium.org> (raw)
In-Reply-To: <20260911-uvc-version-v3-0-604328d8a0dd@chromium.org>
The device announces itself as UVC 1.5, but it only accepts UVC 1.1
controls.
The camera can probably be handled by the automatic uvc_version handler,
but it is more correct to add a quirk and keep some tracking of what
vendors are more or less compliant. Also it might be more robust if we
introduce more UVC version-dependent code.
