MTP A/V Parallel <-> USB Question

[uniTED.LINGdom]

Hope someone can help here (thanks).

I was wondering if anyone has tried to run an MTP A/V Parallel unit using a Parallel-2-USB converter cable (as can be purchased from e.g. Conrad Electronics in Germany) ? In other words, USB side of converter cable coming out of PC -> parallel side of converter cable to MTP A/V. If so, have you had success, or did you encounter problems ? Did you have to do anything specific at the PC side (I can imagine that there is no "Plug & Play" with the MTP A/V Parallel).
OS is WinXP Pro SP3.

I have two MTP A/V Paralell units "just hanging around", but would like to expand my current Express 128 (USB) system.

Thanks,
Ted
