thats not a very fair comparison. USB2.0 is the "new USB", FW800 is the
"new FW" :) but FW is also a better protocol, which means its easier to
get close the theoretical maximum than it is with USB.

i have ENE controllers in my two HP laptops, as do a couple of other
people on LAD. there *were* problems with these in the 2.4 kernel
series, but they were fixable from user-space *and* are gone in 2.6
(AFAICT).

if you were in the US, i could offer you the best prices on RME gear
(i'm a dealer), but with a european location, thats not likely.
