Windows – Gigaware USB to serial adapter not working on Windows 8

serial portusbwindows 8

I'm trying to use a Gigaware USB to serial adapter on my new computer. It worked fine with Windows Vista and XP, but not on Windows 8. It's not working and I get this message under device properties in the device manager.

This device cannot start. (Code 10)

A device which does not exist was specified.

I tried downloading a different driver that I found in this post This device cannot start. (Code 10) – Gigaware USB – Serial Adapter regarding this same problem on here, not sure how I manually add it or if it needs to be downloaded in a specific location to even work. Any help would be appreciated, thanks!

Best Answer

If this is your adapter - then it is based on Prolific PL2303 chipset and your best bet would be to use the drivers from the chipset manufacturer. But if your adapter contains an old revision of the chip - it is just not compatible with Windows 8:

Windows 8 is NOT supported in PL-2303HXA and PL-2303X EOL chip versions.
