Have tried all available ports how do I know which is which 1.1 or 2. Purchased a logitech premium 4 port powered hub is that any good the fellow at Officeworks reckon there OK cost enough if it didn't fix the problem. Can anyone recommend a good basic reader if this doesn't work out. I do want a good sized screen with the zoom function due to poorish eyesight. Don't want to pay too much especially if I have the same problems only want to be able to read books don't need all the other things like diary music etc. Only reason I bought this it was a good deal at the time and iriver have a good name.
