Now why would you do that ?
It'll make your pager ('cat', in this instance) go bonkers!
CTRL+C to stop it

As a typical $User, you won't have permissions
$ sudo fdisk -l /dev/sda
(try these also; replace 'sda' with 'sdb' or 'sdc' -- and try
'/dev/sda1', 'sdb1' etc.... (no quotes))

Good choice - smart...have you tried the boot option 'Linux26' at the
Boot: prompt for Knoppix 3.6? The default is the 2.4 kernel on version
3.6, which has diff support than 2.6 for USB.
Try a newer Knoppix version, though it does sound like either it's the
fault of the actual USB device, or the Mobo/BIOS settings are wrong, or
the hardware's fried...(hopefully not ;-))

* Did you make sure ANY usb device can/does work ?
* Did you alter your BIOS settings, such that you Disabled the USB
ports?
* Check that you didn't knock off (loosen) any internal USB header
wires (inside the case) from the mobo....and/or their corresponding
case connectors.
* How many USB ports do you have?
* Tried them all ?
Check your various /var/log/ files
$ less /var/log/messages
As another suggests;
Check your dmesg output
$ dmesg | grep -i usb
$ dmesg | grep -i sd
$ dmesg | grep -i scsi
$ dmesg | grep -i hd
