I hard soemwhere that if you install the USB 2.0 drivers for my motherboard then you will permanently stuck at USB 1.1. I'm not sure if this is true, but is there any way to check what version of USB I'm using?

Well, you can test it by plugging any new flash drive into it, and if it says "Hi-Speed device in a non Hi-Speed port" (or something like that), then you'll know.

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.

Compatible versions of Microsoft Windows will list USB 2.0 ports and USB devices as "Enhanced" in the device manager.

Additional information about what versions of Windows support USB 2.0 can also be found on document CH000603.

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 product documentation and/or the motherboard documentation.
