This may be easy. Let's make a list.
1. A new install of XP will not have USB working on many machines. http://www.usbman.com notes this dure to missing USB motherboard drivers to simple BIOS settings.
2. Remember that some external USB drives don't work on USB 1.1
3. USB 2.0 doesn't work in XP. You need SP1.
4. Worth repeating. External drives that are in USB 2.0 cases don't always work on USB 1.1. This confound some unless they've seem it some dozen times.
I'm currently running Windows XP pro, and for some reason
I can't connect anything to my USB port. When I hook up my digicam, an error message shows up in the device manager. "USB Mass Storage" pops up, and it says it's not installed. I tried installing it automatically, but windows can't find any drivers. I was running the same OS before, and never had this problem. Then I formateted my computer and installed Windows again, and this problem
came up. Any ideas how to fix it?
