Hi Luis,
I'm just trying this and it works. jackd at 48k*1024*3 produces
occasional x-runs which it otherwise does not.
Jackd even starts up with 48k*64*3 and runs a freeverb in->out with no
x-run! 5mins at the time of writing this email.
Laptop-USB -> Hub (old USB1.1) -> UA-25

I had a PCMCIA USB2 card but I gave that away to a friend, sorry I can
not test this at the moment.
