When I boot Ubuntu 18.04 I get this error in the register:
uvcvideo: Failed to query (GET_INFO) UVC control 4 on unit 2: -32 (exp. 1).
uvcvideo: Failed to query (GET_INFO) UVC control 4 on unit 2: -32 (exp. 1).
uvcvideo: Failed to query (GET_INFO) UVC control 4 on unit 2: -32 (exp. 1).
My web camera works fine.
What could be the cause of this message?
