USB 1.0 Interface

A USB 1.0 (Universal Serial Bus) connector provides a common interface to connect a wide

variety of keyboards, modems, mice, and telephony devices to the VSBC-6. With USB 1.0, there

is no need to have separate connectors for many common PC peripherals.

The USB 1.0 interface on the VSBC-6 is OHCI (Open Host Controller Interface) compatible,

which provides a common industry software/hardware interface.

Note The USB 1.0 interface must be enabled in CMOS Setup.
