My computer still has a USB 1.1. I have been running a scanner out of one port and a 4 port hub out of the other. I have a printer, a card reader and a PDA cradle in the hub. I purchased a really cheap little camera the other day. The specs simply say USB connection. When I try to install it, I get a message that there is not enough power available. I tried taking out the other 3 things in the hub but I still get the message. Is my problem that this is actual a USB 2.0, or might it be something else? This brings me to my next question. Can I replace my current 1.1 card with a new 2.0 one? Do I have to do anything special? As always, thanks for all your help!!
