ho di recente acquistato questo modello di cuffie+microfono usb siccome il microfono integrato nel mio laptop fa abbastanza schifo...
Bene, attacco la cuffia a laptop acceso (Ubuntu 10.04 x86_64, kernel 2.6.32-24 generic) e il sistema va in freeze.
Se attacco le cuffie prima di accendere il computer, il freeze avviene durante il boot. :'(
Provando invece il boot con i vecchi kernel 2.6.32-22 e 2.6.32-23 che fortunatamente ho ancora nel sistema, il sistema operativo parte e l'headset funziona correttamente.
collegando le cuffie, dmesg mostra:
