1. Ignore USB audio 2.0 specification and write your own Linux driver + modification for XMOS firmware
2. Finish implementation of usb audio 2.0 specification for linux driver

I moved in 2 way, but i haven't enough time to finish this work.
Or 3 - disable the Mixer in the XMOS firmware..

Hi guys,

is there any progress on this issue?
I tested with Ubuntu 12 and 14, but the device is only recognized as analogue input - no outputs detected.

With Windows and Thesycon driver everthing works fine.

Built the firmware with MIXER disabled.


Thanks,
Fabian

My understanding is that the driver is not complete, it doesn't have all the units implemented from the USB Audio spec, however, if you disable MIXER (or at least set MAX_MIX_COUNT to 0) I believe it operates.
