This device is working with Kernel 3.1 (in debian wheezy).

1. Check dmesg if the device is registered. You should get something like
this:

[ 400.908425] usb 3-1: new full speed USB device using ohci_hcd and address 2
[ 401.129862] usb 3-1: New USB device found, idVendor=0a73, idProduct=0010
[ 401.129873] usb 3-1: New USB device strings: Mfr=1, Product=2,
SerialNumber=0
[ 401.129879] usb 3-1: Product: Onyx Blackjack
[ 401.129882] usb 3-1: Manufacturer: Loud Technologies Inc.
[ 401.130118] usb 3-1: configuration #1 chosen from 1 choice

maybe you get some of these, too:
[79005.602627] 5:1:1: cannot get freq at ep 0x1
[79005.615632] 5:2:1: cannot get freq at ep 0x82
[79007.303653] 5:1:1: cannot get freq at ep 0x1
[79007.322655] 5:2:1: cannot get freq at ep 0x82
They are no problem!

2. Go to System Settiings (KDE Control Center) click on Multimedia (German
version):
Choose Audio output (Dont know the exact english descriptor) and choose the
Onyx Blackjack device.

Maybe you have to create the following file (dont know exactly if this has an
effect, but its what I did and the device works now
I guess this ones for alsa):
/etc/asound.conf

with the following content:
options snd-usb-audio index=0
options snd-aoa index=1

you will have to change snd.aoa to the driver of your onboard soundcard. snd-
aoa is the Apple Powerbook onboard soundcard.

Maybe you will have to install
apt-get install phonon-backend-xine

3. To use it in audacity with jackd:

- Simply start qjackctl, in Preferences (Einstellungen in german) switch input
device (eingangsgerät) and output device (ausgangsgerät) to Blackjack -> USB
audio, maybe you wish to deselect 'force 16bit' (16bit erzwingen) to record in
24bit and turn the sample rate to 48khz
Sometimes jackd doesnt start properly, then simply start it again and make
sure you plugged in the blackjack first (and enabled phantom power, if
necessary).

- start audacity and switch its soundsystem to jack audio and start recording!

So I think you can consider the mackie onyx blackjack working in linux (debian
wheezy at least. but it should be working in a recent ubuntu with a 3.1
kernel, too).

The devices' sound is really great, especially the preamps.

Have fun
