win2k & usb printer ports

when adding a usb printer the usb ports don’t come up as a choice.the ports work because i can put another device on them and it sees them. the printer works because i can put it on another machine and it is seen also. how can i get win2k to offer usb001, usb002, etc as a viable choice of printer ports. i am on sp4 and current with all other critical patches.
