Anyone know a good 7 port usb hub? One that will pass through 5 powered EHDs, mostly usb 2.0, at a good speed when transferring shows to or from a Hopper 2? I guess it would need on/off switches at each port and I don't know if the hub would need to be powered or not in order to get a decent speed for transferring. Hopefully a hub that is not too expensive. I did buy a cheap non-powered hub that is ridiculously slow.
