uvcvideo 查询失败(GET_INFO)

uvcvideo 查询失败(GET_INFO)

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?
