Possible Solutions
If your drive is connected to a USB 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
transfer rates. For more information, please see sections
Optimizing Data Transfers and
Answers.
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, un-install the drivers and re-install
them.
