The UH101 USB Host Controller is a compactPCI module
providing USB peripheral connectivity to a host computer module on four
front panel connectors. The module provides host USB connectivity when
installed alone or in addition to existing USB host controller hardware.
The UH101 uses a popular NEC host controller chip with USB 1.1 and 2.0
support using the industry standard OHCI/EHCI architecture. A wide variety
of operating systems including Windows, Linux, and others include built-in
support for these devices.
The UH101 makes USB connectivity available to CPCI computers
which do not have such hardware built-in. Moreover, addition of a USB
host controller to a CPCI system with existing USB support may provide
additional bus resources to a peripheral device versus connection through
a downstream hub. In some systems the mechanical robustness of USB
connectivity installed in the CPCI chassis may also be a desirable feature.
These features can be important for instrumentation and control applications
for which the UH101 is particularly well suited.
