[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: *http://ubuntuforums.org/showthread.php?p=9812317 where points to *http://lists.linuxaudio.org/pipermail/linux-audio-user/2010-June/070365.html 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_… -> 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.
