The G70 has a type 'B' usb socket and I'm asking if it is possible to run an external usb hard drive via this socket?

I have a 30GB, 2.5" notebook drive fitted into an external usb caddy. It is self powered and would not therefore take any power through the G70 usb socket. I have used this set up through a Tyros with success, but I think this keyboard has a usb type 'A' socket?

It would be interesting to know and certainly useful. Thought I'd better ask for some views on this subject.
