MH-UH101 USB Host Controller

The MH-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 MH-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 provide built-in support for these devices.

The MH-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 MH-UH101 is particularly well suited.
