Welcome to SysChat.
One way you can identify whether any PC has Hi-Speed USB or not if OS is (Windows ME, 2000 and XP).
1. Right Click on My Computer -> Properties
2. Select Hardware tab -> Device Manager
3. Open Device Manager and expand the Universal Serial Bus section.
4. There should be an "Enhanced" USB host controller present.
In the fig. Shown below you will find other USB Host controllers, these are to maintain backward compatibility to USB 1.1 devices. Likewise USB 1.1 is also forward-compatible with USB 2.0
