I was reading the linux-usb faq and I found:=20 > Sometimes a BIOS fix will be available for your motherboard, and in > other cases a more recent kernel will have a Linux fix.

Usb works, but I have to pass noapic to the kernel. Otherwise I get "device not accepting address" when I plug a device in the usb port. The motherboard has been bought in september. I remember the older mobos had the southbridge b1, which had a faulty usb. My mobo has got the southbridge b2, which works. Is there anything useful I can do? Can you please explain me what "noapic" does? I think it changes the way interrupts are handled, but I'm not sure. Do I miss something when I pass noapic to the kernel? Bye PS: can you please cc your answer to my mailbox? Thank you. --=20 Non c'=E8 pi=F9 forza nella normalit=E0, c'=E8 solo monotonia. --KsGdsel6WgEHnImy Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: Per informazioni si veda http://www.gnupg.org iD8DBQE+nwjyTVwmA6p94JARAk0wAJoCv7W/szBRilvUBnSeN7lXgD3dAgCfeRXq GcRJjOB8sI+cgwCAUnapguk= =n4Kl -----END PGP SIGNATURE----- --KsGdsel6WgEHnImy--
