Can I upgrade the USB port from 1.1 to2.0?
There a such thing as a driver but the problem is some computer require USB 2.0 to be install on XP before SP2 so if you already made the switch before you updated the computer it all most impossible to revert back to SP1 then update then revert back to SP2. I do not know why there is not a simply answer to your question but it all depend on the motherboard. Other then that you could look to buy a USB Card which fit into a PCI card slot that come with a driver for XP SP2 or SP3. I assume you have XP and not a early version of windows. Which the answer will be the same you would have to find the driver.
