That is, I presume, when not powered.
It's a known problem, I understand (don't have any experience myself),
and if this works with the pi under other operating systems, then it's
probably a USB power-negotiation problem. A different hub may work,
but the pi has limited current output on the USB ports, Plan 9 can't
deal with devices that want more.
