sorry for the errors.

Hmm, please do the following:

(0. Switch the device off.)
1. Start usbmon capturing
2. Switch the device on
3. Start alsamixer and select the C400 device

Again, search for Co lines. Is there anything even close to the
control messages you saw on Windows?

Thank you. From a quick glimpse they seem almost identical to the FTU,
just using a different interface/unitid. I will try to send another
patch in a couple of days.

BTW, is the clock source switch still there after applying my patch?
