Fwd: missing input volume controls in MAYA44 USB

[nightmixes <nightmixes@xxxxxxxxx>]

Hi Clemens,

I've added "#define DEBUG 1" in mixer.c, compile and install.

Now, in syslog I have this:

May 21 12:41:28 mint kernel: [  334.392054] usb 3-2: new full-speed USB device number 3 using ohci-pci

May 21 12:41:29 mint mtp-probe: bus: 3, device: 3 was not an MTP device

No errors.

Is there anything else I can do or see with this debug flag enabled?

I think I already owe you a couple of beers.

Regards.

The controls for ID 10 are missing.

Any error messages in the system log?

Try adding "#define DEBUG" at the very beginning of mixer.c to enable
the usb_audio_dbg() calls, or adding more logging to the parse_audio_unit()
or parse_audio_feature_unit() functions to see where it aborts creating
the controls for unit 10.

Clemens
