Most all powered USB hubs out there should work, no problem. I know I've had success using several differently labled lowcoast brands.

I have also used a separate wallwart on my small black pgmusic USB drive in the past, tip is positive here also, my wallwart is spec'd for 5.1VDC and 1.8A. While the drive itself is spec'd at 5V, I don't think that extra tenth of a volt will cause it any undo pain **gg**
