I am having trouble with the US122 in playback and duplex mode. In capture mode, it is working.
This problem occurs on (at least) Linux arial 3.14-1-686-pae #1 SMP Debian 3.14.7-1 (2014-06-16) i686 GNU/Linux
I note that my computer uses the much-maligned Intel Corporation 5 Series/3400 chipset (rev 05), but I have a UK£12 5.1 out/2.0 in audio adaptor which works in either capture or playback (although not in duplex). Also, booting an old kernel:
Linux arial 3.2.0-4-686-pae #1 SMP Debian 3.2.57-3+deb7u2 i686 GNU/Linux
or
Linux arial 3.10.11 #1 SMP Wed Oct 2 19:26:59 BST 2013 i686 GNU/Linux
both seem to support full duplex operation. This is therefore a regression between 3.10.11 and 3.14-1 (at least, something on my system has regressed and I am suspecting the usx2y module).
dmesg tells me:

I used to use these interfaces with jack in duplex mode, but this is no longer possible.
Running up audacity for a test, capture from the US122 works fine, but once the US122 is selected for playback, audacity pops up an "Error opening sound device". Further attempts to record (even capture-only) result in corrupted, high-amplitude noise.

Other info which might help (a bit noisy, because I'm not sure exactly what's wrong) follows.
