You already have two USB ports available, USB 1 and 2 (see external connec-
tors). The internal USB connectors allow you to add on an optional kit to ex-
pand the total number of USB ports available. The 845D-AV has two internal
USB connectors (CN30 and CN31). This enables you to use an extra two USB
devices. Cable for these additional connectors needs to be purchased sepa-
rately.
Note: These are not the standard USB connectors you find on the ATX PC99
connector. To connect USB devices you need to use an expansion cable
(purchased separately) that ends in a standard USB connector. Ask your re-
tailer for more details.
