Certainly:

Now, there's something. But still nothing for fdisk:
hardy1 at hardy1-laptop:~$ sudo fdisk -l

Disk /dev/sda: 80.0 GB, 80026361856 bytes
255 heads, 63 sectors/track, 9729 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

In mount I found this line:
procbususb on /proc/bus/usb type usbfs (rw)

But with nothing in fdisk, what can I do?
