Hi Lars,
Thanks for your analysis! This device is supposedly USB audio 2.0 class compliant. It also supposedly works with Linux, although I found one report of it working intermittently until a kernel recompile, and another where it stopped working after a kernel upgrade, but mostly reports of it working with various Linux apps (I don't have a Linux install to test on). I can say it is correctly recognized on Windows, and works.
I tried lsusb -v, but that failed to detect it too, ending with:
[C:\]lsusb -v > lsusb.txt
can't get debug descriptor: No such file or directory
can't get device qualifier: No such file or directory
can't get debug descriptor: No such file or directory
can't get device qualifier: Invalid argument
can't get debug descriptor: Invalid argument
One of the reasons I got this device in the first place was that Wim Brul used a virtually identical device (UMC204HD - same with MIDI I/O added) to develop his audio recording app.
I have a laptop with USB2 ports I'll give your drivers a try with later today... thanks again!
Regards,
