Hello there,

Trying to set up my good old Tascam US-122L again on a fresh Ubuntu Studio.
I got it running with older Ubuntus, but it seems that the bug is back again with Linux 3.x

Actually this is 3.13.0-34-lowlatency, I've apt-installed alsa-firware-
loader, snd-usb-122l is available, but nothing showing in
/proc/asound/cards or /proc/asound/modules.

I've created ~/.asoundrc with :
pcm.!usb_stream {
	@args [ CARD ]
	@args.CARD {
		type string
		default "1"
	}
	type usb_stream
	card $CARD
}

ctl.!usb_stream {
        @args [ CARD ]
        @args.CARD {
                type string
                default "1"
        }
        type hw
        card $CARD
}

cat /proc/asound/modules:
 0 snd_hda_intel

cat /proc/asound/cards
 0 [Intel] : HDA-INTEL - HDA Intel
   HDA Intel at 0xf0700000 irq 44

When I plug it in I can see all the leds flashing for 0.1 sec and then nothing.
What shall I do?
Thanks

Title:
  snd_usb_us122l is not working even if supported from kernel.

Status in “linux” package in Ubuntu:

Bug description:

  jackd -RP50 -dalsa -dusb_stream:0 -r44100 -p64 -n2
  sudo jackd -dalsa -dusb_stream:0 -r44100 -p64 -n2

  Maybe this helps. As far as I understand the card is recognized but
  not working for playback or record.
