I tried more than an USB 1.1 soundcard on different operating systems, 
and I think you can't go beyond 5.6ms, setting -p64 -n4 in jackd (this 
is what I use with my UA-25). But even that is less latency that I used 
to get with my old PCI soundcard (EgoSys Waveterminal 24/96) on WinXP. 
This was an expensive professional soundcard when I bought it six years ago.

It's just my experience, but with gnu/Linux, jack and the alsa-usb-audio 
driver you get far lower latencies than when using other operating systems.
