2.7 USB Connector
The USB connector is used for connecting any device that conforms to
the USB interface. Many recent digital devices conform to this standard.
The USB interface supports Plug and Play, which enables you to connect
or disconnect a device whenever you want, without turning off the com-
puter.
The UNO-2052E provides two connectors for USB interfaces, which
gives complete Plug & Play, and hot swapping for up to 127 external
devices. The USB interface complies with USB UHCI, Rev. 1.1. The
USB interface can be disabled in the system BIOS setup. Please refer to
Appendix A.6 for its pin assignments.
