I suspect that the device firmware has crashed, possibly as a consequence of requests related to the audio interface. Zhengyang, could you try to blacklist the snd_usb_audio driver to avoid it being automatically loaded, and see if the camera then works (after unplugging and replugging it) ? If it doesn't, please provide the contents of the kernel log. > The Kernel probe also has similar troubles: > > [ 31.553926] usb 1-1: Found UVC 1.00 device HIK 2K USB CAMERA (2bdf:0281) > [ 32.065510] usb 1-1: Failed to query (GET_INFO) UVC control 11 on unit 1: -110 (exp. 1). > [ 32.577665] usb 1-1: Failed to query (GET_INFO) UVC control 12 on unit 1: -110 (exp. 1). > [ 33.089610] usb 1-1: Failed to query (GET_INFO) UVC control 2 on unit 2: -110 (exp. 1). > [ 33.601620] usb 1-1: Failed to query (GET_INFO) UVC control 3 on unit 2: -110 (exp. 1). > [ 34.113672] usb 1-1: Failed to query (GET_INFO) UVC control 7 on unit 2: -110 (exp. 1). > [ 34.625635] usb 1-1: Failed to query (GET_INFO) UVC control 8 on unit 2: -110 (exp. 1). > [ 35.137673] usb 1-1: Failed to query (GET_INFO) UVC control 10 on unit 2: -110 (exp. 1). > [ 35.649581] usb 1-1: Failed to query (GET_INFO) UVC control 5 on unit 2: -110 (exp. 1). > [ 36.161693] usb 1-1: Failed to query (GET_INFO) UVC control 11 on unit 2: -110 (exp. 1). > [ 46.401833] usb 1-1: UVC non compliance - GET_DEF(PROBE) not supported.
