How do I determine what version of USB I'm using?
Is the USB device or USB ports on computer labeled as USB Hi-Speed?
Many devices and computers using USB 2.0 will indicate if products are USB 2.0 ready or that they are USB 2.0 Hi-Speed. Computers and devices that have this are Hi-Speed are USB 2.0 compatible.
Did you buy your computer before 2001?
USB 2.0 was introduced in 2001, if you purchased your computer before 2001 it is likely that you are using USB 1.1 or 1.0.
Device Manager lists USB as Hi-Speed
Compatible versions of Microsoft Windows will list USB 2.0 ports and USB devices as "Enhanced" in the Device Manager.
If after following the above recommendations you are still unable to determine enough information about what version of USB your computer has refer to the USB or the motherboard documentation.
