"My PC has full [sic] USB support but no USB connectors"

So that's hardly "full" USB support, then, is it!!???

Probably, all you need is (a) connector(s) to fit into the back of your PC and plug onto the USB header(s) on your motherboard.
Look at any PC bits supplier for this; and, of ccourse, the Manual for your motherboard.

BTW: What's the 8052 connection here?
