Situazione: pentium III, 384 MB di Ram, cpu 933 mhz, 2 ingressi usb 1.1.
Ho aggiunto una periferica usb 2.0 pci, ma non riesco a far vedere alla
mia Debian Sarge 2.6.8 la mia penna usb e neppure nessuno dei due hard disk esterni ( che invece vengono riconosciuti perfettamente dagli
ingressi usb 1.1)
Ho installato usbview che riconosce la periferica usb 2.0.

Da notare che all'avvio prima della schermata di login appare:
"usb 4-4: device not accepting address 4, error -110"
Inoltre in /var/log/dmesg:
"USB Mass Storage device found at 3

Ma se provo a fare:
Sarge:/home/*****# mount -t vfat /dev/sdc /media/usb2
mount: special device /dev/sdc does not exist

Che fare?
Grazie in anticipo a chi mi vorrà aiutare
