I'm trying to use a Gigaware USB -> Serial adapter that worked fine on Windows XP on Windows 8. It's not working and I get

in device manager. It says the drivers are up to date. What should I do?

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.

This tool WILL work if you are receiving the (Code 10) error. Despite all the comments about it not working on Windows 8/8.1, there is a simple way to make it work: Fake PL2303 – how to install on Windows 8.1

You need to downgrade the driver to the 2008 3.3.2.102 version and choose it specifically as per this page:

Or the duplicate answer on Super User page Gigaware USB to serial adapter not working on Windows 8.

I found that this was needed when using the ADAfruit USB-to-TTL adapter cables.

The only issue is that every time you remove the device you will have to go through the same painful exercise as Windows doesn't retain the driver association details.

Download this driver from the Windows Update Catalog. Then manually add the driver using Device Manager.

I also download the driver listed (AMD64_X86-en-20357822_453c563f64689a47c9be3972b95db24900db3798.cab)above from Microsoft and manually added it. You must remove the Svk2pl.inf from the .cab, disable the device, select the .inf file. After you are done the will show up as Gigaware USB to Serial Cable (COMx) x=port. If you move the connection to another USB port you have to make the same change or you will still have the problem. The device works great now. I used the PL203CheckChipVersion.exe to verify my chip version, I am using PL-2303 XA / HXA chip. This tool will not work if you are receiving the (Code 10) error.

The adapter you are referring to is not compatible with Windows 8, and even updating the drivers will not make it work either since it most likely has the old version of the Prolific chipset. A solution would be using an FTDI based USB-to-serial converter which has better drivers and is compatible with Windows 8.

I also just had this problem, and I downloaded the 'Windows Update Catalog' after uninstalling and reinstalling driver. I went to Device Manager and updated the driver with the file I downloaded.

It works great now.
