Latency in 1.1 vs usb 2 shouldn't be significantly different as I
understand it. usb 2 just allows higher bandwidth - so more channels
or 24bit vs 16bit. Just depends on whether the interface is properly
supported in linux.
I have used a USB 1.1 IF on my netbook running at 800Mhz (half speed) and
was still able to run the IF at -p 64 -n 2 (2.67 ms Latency) without
xruns. I did have to back the latency off if I ran too many softsynths or
too many effects, but even double that is not bad. -p 64 with USB 2
devices seems to be the lowest too. I run into memory problems before CPU
use problems in general with only 1G memory :)

My experience with USB audio is limited, but USB 1 on mac, for live
processing, I have found to have unusable latency.
