I'm pretty sure most generic USB 2.0 hubs will work just fine. I've seen no name ones used on the 360 with no issues (as long as they are powered). I also use my the 4 port built in USB 2.0 hub in my monitor (Dell Ultrasharp 2408WFP) for the 360. It's worked for USB keys, USB hdd's, Play and Charge cables and USB keyboards though the monitor's hub before with no issues whatsoever.
