Q: How do I determine whether or not my system supports USB 3.0 or USB 2.0?

A: Refer to your USB card documentation or contact your USB card manufacturer.

Note: If your USB 3.0 or USB 2.0 controller is built in to the system motherboard,

be sure to install the appropriate chipset support for your motherboard.

Refer to your motherboard or system manual for more information.

Q: What happens when a USB 3.0 or USB 2.0 device is plugged into a USB 1.1 port or

hub?

A: USB 3.0 and USB 2.0 are backward-compatible with USB 1.1. When connected to a

USB 1.1 port or hub, a USB 3.0 or USB 2.0 device operates at the USB 1.1 full speed

of up to 12 Mbps.

If your system includes a PCI Express slot, you can achieve USB transfer rates by

installing a PCI Express adapter card. Contact the card manufacturer for installation

procedures and more information.
