[LAU] USB audio interface and a buggy USB controller

It seems that my new laptop has a buggy USB controller (lspci says 'Intel Corporation 5 Series/3400 Series Chipset USB2') and this causes JACK to fail in 'duplex mode' and 'only recording mode'

$ /usr/bin/jackd -dalsa -dhw:2 -r44100 -p1024 -n2
ALSA: could not start playback (Broken pipe)
DRIVER NT: could not start driver

I have an Edirol UA-25EX.

I read about this problem in:
where points to

Any idea to deal with the problem? What to do?
1) Try to have the money back
2) Try to use a USB_2_ExpressCard converter like this one?

http://www.delock.com/produkte/gruppen/Express-Card/Delock_Express_Card_to_2x_USB_20_66202.html -> it says linux compatible

If this works, the performance will be similar, better or worst?

Thanks in advance,
Joan Quintana

PD. I checked a lot of things and grasped a lot of information thinking in my new laptop for audio production... but I never would thought in the USB chipset.
