2.22 USB Connectors (CN9/CN11)
The HSB-657I board provides four USB (Universal Serial Bus)
interfaces, which give complete plug and play and also hot
attach/detach for up to 127 external devices. The USB interfaces
comply with USB specification rev. 1.1 and are fuse protected.
The USB interfaces are accessed through two 10-pin flat-cable
connectors, CN6 & CN8. The adapter cable has a 10-pin connector
on one end and two USB connectors on the bracket on the other
end.
The USB interfaces can be disabled in the system BIOS setup.
