I first published this question to Stackoverflow but unfortunately it went unanswered.
I am having problems with a USB3 UVC camera (Generic camera, with a Sony IMX179 sensor and, I believe, a Realtek chipset) under Linux (Kernel Version: 4.19.6 - older kernel versions have been also been tested as well, ie: 4.16.x). The VID and PID for this camera is 0bda:3038.
If this camera is plugged into USB2 then it works correctly. However, if this camera is plugged into USB3 then the camera does not work.
I have looked at the logs produced with
dmesg when plugged into both USB2 and USB3 ports. The primary differences (for USB3) are the two following lines:
Code:
[ 4066.390477] uvcvideo: no class-specific streaming interface descriptors found.
[ 4066.425097] uvcvideo: No streaming interface found for terminal 3.
[ 4068.819466] uvcvideo: Suspending interface 0
From my research, it appears that the message "No streaming interface found" indicates that v4l2 is unable to find a driver. Although, v4l2 has no problems with finding a driver when connected to USB2. Another difference is that under USB3, v4l2 is unable to parse the pixel formats. (YUYV and MotionJPEG) but can find the various camera controls (V4L2_CID.GAIN etc).
I have switched on additional logging (
echo 0xffff > /sys/module/uvcvideo/parameters/trace) and have attached the dmesg logs below. I also attach the output of lsusb -v for this device. I would be grateful if somebody would be able to offer any help on getting this device to be recognised on USB3.
Many thanks
Amanda
Logs as follows (very long, I'm afraid). The first log is lsusb -v, the second is dmesg when connecting to USB3 and the third, dmesg when connecting to USB2
lsusb -v
