uvcvideo 查询失败（GET_INFO）

Question

当我启动 Ubuntu 18.04 时，寄存器中出现此错误：

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).

我的网络摄像头运行正常。

出现此消息的原因可能是什么？
