I have a computer w/ USB2.0 connectioins..however my scanner and printer are only USB1.1 devices..I need to connect them to my computer through a USB hub...Should I get a 1.1Hub..or a 2.0Hub??? Will it make that much of a difference if I get 2.0vs 1.1 Hub..I just wouldn't know because the devices themselves are 1.1...Help please. thanks
