Well, it's the end of the year, and I ordered a USB Console Cable to allow easy access to my Pi from my laptop while on vacation. Unfortunately, my Laptop runs Windows 8.1, and the drivers from the linked Prolific website do not work (10/23/2013 WHQL) - the device showed up in de Device Manager with a warning triangle beside it. When I double-clicked on it, it had a message stating "This device cannot start. (Code 10)". I then installed the driver on my wife's desktop running Windows 7, and ran the Chip Version Checker which is included in the driver folder. This identified the chip being used in the USB Console cable as a "PL2303 XA/HXA" chipset. Upon returning to the Prolofic website, I noticed (in Red letters) a message stating: "Windows 8/8.1 are NOT supported in PL-2303HXA and PL-2303X EOL chip versions."
OK, so it looks like the chipset in these cables are end-of-life and will not work with Windows 8 and up, which was not stated on the website when I purchased the cable. Do you have a cable which is compatible with Windows 8? If not, can I return the cable for credit?
