You could try and see how far you get with pyusb, the wrapping for libusb. However, any decent usb2<somewhat>-adapter should register itself as device of the mapped kind. For example, usb2serial-converters appear as COMx:-ports. So I *guess* you are having driver-problems if the converter doesn't show up as parallel port. Apart from that, you might consider using products like atmel's USB-Key or similar to attach a microcontroller to the USB-port that then will use it's own ports to control the motors.
