This series provides two USB ports USB0 and USB1 on board sup-
porting various USB devices. In addition, two USB pin-headers are

by using two additional USB cables. Users can order the optional USB
cables from your mainboard dealer or vendor.
When plugging the USB cable to USB Header, users must make sure
the red wire is connected to Pin 1.
All 6 USB ports are compliant with 1.0 / 2.0 USB Bus. USB 2.0 supports
Win 2000 and up (exclude Win9X / Me). USB 1.0 / 2.0 drivers are pro-
vided in Support CD for user's installation.
