Subject: [PATCH] media: uvcvideo: Add quirk for Luxvisions RGB Camera (30c9:0122)
Date: Thu,  3 Sep 2026 16:11:45 +0800	[thread overview]
Message-ID: <20260903081145.8382-1-rh_king@163.com> (raw)

The device binds cleanly but delivers no image data; USB autosuspend is
suspending the streaming endpoint. Disable autosuspend for it.

Issue found on Lenovo ThinkPad X13 (codename Zelda, Intel); confirmed
working with this quirk.
