When you plug in the USB drive, lines should be appended to the dmesg of 
the kernel identifying the device - or any errors. Please post that.

You may need ehci if this is USB 2.0, but I think it would otherwise 
fall back on either ohci or uhci.

See comment above on dmesg. You don't get all the relevant info by 
grepping for usb.

Is that with the device plugged in? If so, seems logical that there is 
no device in /dev because it is not found.
