The old driver "Prolific windows-XP driver version 2.0.2.1 ()" works on all 3 without any problems at all. Tested on 3 computers (one Vista and two XP) with no luck. Driver Installer program from Prolific Support.

Even tried cleaning out the registry to make sure no remains of the old driver was left. This section will guide you on how to install the PL-2303 Windows Driver. I have a slightly different cable but still with the Prolific chip, and the new driver does not run at all. If you use the recommended driver, and still have communication problems, make sure to report windows and driver version as well. In many cases it appeared that VemsTune communication was bad when in fact the prolific windows driver lost data and reported bad about the buffers.
Your driver might be broken even if it works for some applications, or work "sometimes". Now that we met more cases, made more investigations and know for 100%, fortunately prolific has a newer driver for download that works so much better. we contacted prolific about the PL2303 driver when we were only 99% sure that the XP driver was broken, but we never received a reply.Unfortunately the notification either didn't happen, or was unsuccessful. That way they would learn about the situation and the need to upgrade driver (it takes 3 minutes for an enduser to upgrade after 500 mins of headache caused by apparently application problems, and maybe 0.01 min / sold cable for the manufacturer to update the zipfile on the CD).

Maybe it's a good idea to notify manufacturers who purchase millions of these chips with broken drivers released. Somehow the information did not make it to the 10 cable manufacturers prolific sells millions of these (HW-wise great!) chips. The broken 2003-2005 drivers are more common than one would think, included on many CD's even several years after prolific found out it's broken and fixed in new releases.
