This looks like your usb support isn't working do other usb devices work?

You can load usb-storage once either before or whilst the device is 
plugged in and leave it loaded.

When I plug in my memory stick this is what I see.

usb 3-1: new full speed USB device using address 2
Initializing USB Mass Storage driver...

Are there any other errors in dmesg as the machine boots?
