Ho un problema con le periferiche USB2 che funzionano alla velocità di USB1.
Uso slackware 11.0 con il kernel 2.6.17.13.
a parte che ogni tanto mi da problemi di IRQ e le periferiche non si connettono apparentemente sembra tutto ok ma sia chiavette che masterizatori che harddisk vanno a 1Mb/s.
Posto l'output, magari qualcuno più esperto riesce a trovare il problema:
