Power prevents problem product

I've introduced a powered usb hub into my system, to hopefully stop the problems I've been having with my usb mouse and network adapter. Under Windows, the mouse frequently needs unplugging and reconnecting, and the network adapter disconnects and has to be told to reconnect to the wireless network. Under Linux, this seems to cause an even more severe problem, with the entire system freezing.

I put the powered hub on last night, and had no problems. I've left the computer on all day today, so if when I get home it is still working, the problem is probably solved.
