The tool referred to can be found at
USB troubleshooting click the usbview.exe link to download the tool.

When you plug the cable in then right click My COmputer / Porperties /Hardware/ Device Manager/ then Ports - find your device - if not could be shown under Unknown Device '?'.
When found double click to open, click Details tab, The drop down box should say Device Instance ID, and the information you need is shown in the box below, (so copy it manually into notepad for reference).

If you download a driver off the web, open the .INF file by right click / edit or something.
do a find on the VID word, then see if the same VID / PID numbers are present in the driver, if not you need to find a later or different driver.
Hope this helps
