works great, I have a powered usb hub and I use it for my wifi thumb drive, wireless keyboard and a second external hard drive. All work great together. I use one 500GB hard drive for my music and family photos and the 2TB drive for all my movies.
Sorry about that, I can’t remember what brand or model number, it’s just a standard 4 port USB hub that is powered. I think the deal here is that the WD Media player only has enough power to accomidate maybe one un-powered USB external hard drive. I didn’t take any chances so I use all products with power. I have two external hard drives, one in the USB port 1 and the powered hub on the second USB port 2 and connect my second external powered hard drive and my WIFI wireless adaptor and wireless keybord. Hope this helps. I think you could use any USB powered hub.
