Frequently Asked Questions — USB Information
Q: What is Hi-Speed USB?
A: Hi-Speed USB is another name for USB 2.0, which provides transfer rates up to
40 times faster than USB 1.1. Upgrading to USB 2.0 is highly recommended
because of the significant reduction in file transfer time versus USB 1.1.
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-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 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
Mbps.
Q: Can USB 1.1 cables be used with USB 2.0 devices?
A: Although USB 1.1 cables work with USB 2.0 devices, it is recommended that
USB 2.0 certified cables be used with USB 2.0 peripherals and USB 2.0 PCI
adapter cards.
