Hi Laurent,
Thank you very much for the reply.
I tried it on a Windows 10 computer and it worked fine without
installing any additional software.
Also managed to capture USB traffic on Linux (didn't capture on Windows yet).
I don't see a lot of traffic, most of the messages are USB and USBHID
protocol messages for GET_STATUS, SET_FEATURE, GET_DESCRIPTOR etc.
There is only one USBVIDEO protocol message for GET_CUR (0x81). Seems
like this request fails the error "No such file or directory (-ENOENT)
(-2). Does this sound like a bug in firmware / cause for the error we
saw in dmesg output?
Here's the full text of USBVIDEO request and response:
