Quite true. That is the number they list. However, that *is* in excess of the USB 2.0 spec. That number is in line with the USB 3.0 spec, but the port on the RoboRIO isn't listed as a USB 3.x device. So, yes, you *should* be able to get by with it. But, even though the RoboRIO can supply 900ma, it doesn't mean that your hub is built to handle that kind of current inbound from a single USB port. You'd still be better off with a powered hub, IMHO.

Good luck,

Mike
