The Electrix Ebox-44 is a new USB interface, but the MIXER_UNIT descriptor is broken and refers to a non-existing unit_id.
I'd suggest to change the code to not abort if a unit doesn't exist.
It would seem a little strange to skip over the error for one specific condition to accomodate a specific device -- when the rest of the code does not generally do this?
It's still possible to complain about the broken firmware, but there is no reason to prevent the user from accessing the PCM streams and all other mixer controls just because one descriptors happens to be wrong.
The patch for this is relatively simple, I put it below for reference. The device can then be used; audio streams and a mixer are available.
But I'm not sure the resulting mixer is correct or complete so I'm in the process of getting access to one of these devices -- will allow me to check everything. I'll post more information when I have it.
Thanks
