Although I have usb1 support & use it for various connections (scanner,adsl external modem etc. m/b 2 connections) I was thinking of adding a usb2 pci card to a spare slot, but after looking at my M/B book, I,m not sure if I can. Although there is an option to add more usb if required (using 2 x 10 pin headers) I can,t see any mention of USB2. Looked at various online companies (scan, PC World, can only find usb1 cards that use header connections) Although it is quite an old M/B I don,t want to change it just for a faster usb connection. Sorry to ramble on, hope somebody can help. Cheers Nipsen.
