My Friends: I have a Compaq Evo Pentium 4 desktop running Win XP Pro SP2. I plugged a 4.0 GB USB memory stick (USB 2.0) but the stick does not show up in My Computer, Device Manager or Disk Management. The stick works on my Pentium 3. The specs for this computer shows the USB supports a 1.1 USB. Is this why it is not reading my stick? How can I fix this? Thanks or any help.
