Usb Interfaces - Unisys Aquanta CP Series Configuration Manual

USB Interfaces

The Universal Serial Bus (USB) is expected to become the standard for low and
medium speed peripheral connections. Its flexible architecture, 12 MBs speed with a
1.5 MBs sub-channel, and Plug and Play features, support 127 different physical
devices, including the USB Keyboard, USB Mouse, USB Monitor, USB Digital
Camera and USB CTI (Computer-Telephony Integration).
A dual channel USB connector is located on the back panel of the system that provides
high speed, ease of use, and Plug and Play connectivity to a future generation of
peripherals.
USB is not supported by Windows NT 4.0. Future versions of Windows NT are
expected to support USB.
