Q: How do I determine whether or not my system supports USB 2.0?
A: Refer to your USB card documentation or contact your USB card manufacturer.
Note: If your USB 2.0 controller is built into 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 2.0 device is plugged into a USB 1.1 port or hub?
A: USB 2.0 is backward-compatible with USB 1.1. When connected to a USB 1.1 port
or hub, a USB 2.0 device operates at the USB 1.1 full speed of up to 12 Mb/s.
If your system includes a PCI slot, you can achieve Hi-Speed USB transfer rates by
installing a USB 2.0 PCI adapter card. Contact the card manufacturer for installation
procedures and more information.
