Sobre puertos USB
Hola!
Vereis, tengo una placa base con 10 puertos (8 traseros y 2 delanteros)
Usb 2.0 pero se reconocen solo 4.
Si cargo el modulo ohci, salen 10 puertos 1.1 y con el ehci solo 4 (2.0).
como puedo hacer para poner los 10 a 2.0?.
pego el lspci:
angelja@debian:/usr/src/linux$ lspci |grep USB

(rev a2)
0000:00:02.1 USB Controller: nVidia Corporation: Unknown device 005b
(rev a3)
pego tambien la salida de dmesg:
