It looks like a big usb stick with slots for memory cards. It's not something silly like the device saying it only needs 100mA while in reality it needs 200mA?

I have ehci built-in, how can I force full speed? Hm, in the BIOS maybe. I'll try it with my neighbours' pc later today, if I've the chance.
