Problem Question Answer

e drive is not run-

ning noticeably faster

when connected via

Hi-Speed USB 2.0.

Is the drive connected to a USB 1.1

port on your computer, or to a USB

1.1 hub?

If your drive is connected to a USB 1.1 port or hub, this is normal.

A Hi-Speed USB 2.0 device can only operate at Hi-Speed USB

2.0 performance levels when it is connected directly to a Hi-Speed

USB 2.0 port or hub. Otherwise, the Hi-Speed USB 2.0 device will

operate at the slower USB 1.1 transfer rates.

Is the drive connected to a Hi-

Speed USB 2.0 port on your

computer?

Check to see that the Hi-Speed USB 2.0 drivers for both your host

bus adapter and device have been installed correctly. If in doubt,

uninstall the drivers and re-install them.

Does your computer or operating

system support Hi-Speed USB 2.0?

See section 1.2, Minimum System Requirements.
