Guys, this is how I fixed the problem:

1) get yourself a USB cable
2) Cut off the square end of USB cable and strip back to the wires
3) Find the RED wire and cut down others (not needed)
4) Remove outer shell/casing from dongle
5) Take RED wire from USB cable and solder it to pin 20
6) Replace casing - take care in doing this
7) I then used a hot glue gun to seal area where USB cable coming out.
8) Plug dongle into LPT port
9) Plug USB into USB port on pc
10) EnJoY the use of DCT4 calculator!!

To help you find pin 20, I have a pdf document with pin out.

Please view it here:

Please note; I take no responsibilty or accept no liability for any damages to your dongles or pc while attempting this modification. It worked 100% for me. If in any doubt, seek further advice.
