I'll shorten it up somehow or put it on the website and drop the link

Stuff from the message that was too big.
Below it is cat /proc/asound/card1/stream0 and below that is cat
/proc/asound/card1/stream1. According to all of this(including the
unlisted lsusb -v), it supports 24-bit and 16-bit. At 24-bit@48KHz, it
is suppose to have 4in and 2out, at least according to M-Audio and when
used in OSX. Which I have no problem with using it in OSX, except that I
have crashed OSX twice with unplugging and plugging it from the USB
port. I have yet to have a problem with it doing this in Linux. Plus, I
have some plug-in bugs in Ardour in OSX. Also, as seen in cat
/proc/asound/card1/stream1, it is playing (via beep-media-player) at
44.1Khz and 24-bit format.

Is it possible that Jack is sending the right information to get the
sample format. I think I read somewhere that jack sends out stuff like
S24_LE and according to the cats, the device identifies its 24-bit and
others as S24_3LE.

You can see which sample rates are supported by running:
lsusb -v
for more info :
lsusb --help
Cheers.

Tried it, but no luck. Thanks. I think I might toy around with the
alsa-jack driver. It may be jack doesn't like how the sample formats
are done on the omnistudio. Even though I have alsa playing through
it fine still.

I'm not sure what jack's problem is, but it returns this no matter

~$ jackd -dalsa -dhw:1 -r48000 -p1024 -n2 -i4 -o2
try this: jackd -dalsa -dhw:1 -r48000 -p1024 -n2 -i4 -o2 -P
Your device may have different sample rate capabilities for
playback and capture and jackd may not be able to figure that out.
Cheers.
