I'm trying to get a Tascam US-122L USB 2.0 Audio/MIDI Interface working with jackd.
The correct kernel modules seem to load when I plug the device in:
$ lsmod | grep us122l
snd_usb_us122l 23020 0
snd_usbmidi_lib 29476 1 snd_usb_us122l
snd_hwdep 17709 2 snd_usb_us122l,snd_hda_codec
snd 78957 18 snd_usb_us122l,snd_usbmidi_lib,snd_hda_codec_analog,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_pcm,snd_rawmidi,snd_seq,snd_timer,snd_seq_device
ALSA seems to detect the card:
$ cat /proc/asound/cards
0 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0x60000000 irq 16
1 [US122L ]: USB US-122L - TASCAM US-122L
TASCAM US-122L (644:800e if 0 at 001/004)

The card also shows up in qjackctl, but when I select it as interface and try to start jackd, I get the following error:

Tried to modify /etc/security/limits.conf and ~/.asoundrc according to the answer to this question, but it didn't solve the problem. Currently they look like this:
$ cat .asoundrc | grep -v \#
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 /etc/security/limits.conf | grep -v \#
@audio - rtpio 99
@audio - memlock unlimited
@audio - nice -10
The same happens with Xubuntu 14.04 and Ubuntu Studio 12.04.
Any suggestions are greatly appreciated. This card should be supported as far as I know.
