Hi! The good news is that I have 122mkII to play with, the bad news is that it doesn't work with the snd_usb_122l driver.
The probe function fails most likely in usb_stream_start(&us122l->sk),
The dmesg output:
... status=-2 status=-2 us122l_start error -14 snd-usb-us122l: probe of 1-2:1.1 failed with error -22 usbcore: registered new interface driver snd-usb-us122l ...
I've set up a windows machine with usbsnoop and captured the init log (I could upload it somewhere if anybody is interested). I would probably be able to help fix/write the driver with some guidance. Just now I'm trying to understand the log...
PS: I've send this mail to alsa-devel a couple of days ago, but without being subscribed, does anybody do the screening on incomming mails?
