Perhaps your USB drive is not recognized or broken.
Use the "modprobe" command.
What is the brand and type of your USB Flash drive?

================================
I am going to put the commands you need to type in square brackets. You need to type them in exactly as I say or it probably won't work. Please do not type the [] as part of the commands
1. Log in as a normal (not root) user
1.5. Open a terminal window (Right click back ground -> Terminal)
2. Switch user to root [su - root]
3. Insert the memory stick into a USB port
4. Type [modprobe \*]
5. The system should identify the make/model of your USB stick.
6. Type [mkdir /stick] to make a new, empty directory
7. Make the directory world accessible [chmod a+rwx /stick]
8. Connect the memory stick to the directory [mount /dev/sda1 /stick]
You might have some trouble here. If you use other USB devices, then the device name for the memory stick might be /dev/sdb1 or /dev/sdc1. If all goes well, you should just get a # prompt back.
9. If you have files on the USB stick, you can see them with [ls /stick]
10. Leave the switch-user shell [exit]
11. You should now be able to use the memory stick simply by copying files to/from the /stick directory.
