Hello,
I've been hacking to get Rane SL-4 USB audio
(http://dj.rane.com/products/sl4-for-serato-scratch-live) which have 4
Input and 4 output channel to work with ALSA. After digging the lsusb
and snoops I have separated endpoints for input (0x82) and output
(0x06). They are just USB Isochronous I/O.
I have compiled kernel and tried to get USB-quirks to work with this but
then I have to admit that even Reloop Play seems be very similar it
doesn't do the trick (No error but card doesn't come up eather) nor
using Ranel SL-1 approach which just shoots the error
[ 3555.009349] usb 1-5: Audio class v2 interfaces need an interface
association
[ 3555.009373] snd-usb-audio: probe of 1-5:1.0 failed with error -5
[ 3555.009394] usb 1-5: cannot find UAC_HEADER
[ 3555.009401] snd-usb-audio: probe of 1-5:1.1 failed with error -5
[ 3555.009421] usb 1-5: cannot find UAC_HEADER
[ 3555.009427] snd-usb-audio: probe of 1-5:1.2 failed with error -5
If I need interface association how to do that? Trying to adjust mixer
values in mixer_maps.c.
If someone have a time to give some guidance if this doable with Quirks
or do I have to write some more specific driver? I attach lsusb below here.
HID device seems to be adjusting buffer size and 48 Khz and 96 Khz output.
