Ok, revisiting this issue. Is there updated instructions or any tips for getting this driver to work on Win 8.1?

My GMC-320 displays as this and there is no driver rollback option. I tried updating it with the update driver option which didn't work either.

Try to change USB port, to test, connect your GMC device directly on your PC, and not after a Hub.
After if it doesn't work, may be that the windows registry of your windows 98 must be corrupted, it happened easily with this version of windows.
forget the driver that I indicated to you, it apparently has specificities. and prefer that of EmfDev.

you can try to do the following operations in the following order:
- uninstall the driver
- disconnect the GMC device
- reboot windows
- install the driver again
- reconnect the GMC device




There is only 1 other USB device connected (my wifi dongle). I have been connecting the GMC-320 directly,
and I tried using the older legacy USB 2.0 instead of the blue 3.0, but it still didn't work.
I even tried using the old USB driver (#19 on the download page). I'm using Windows 8.1, I don't know why you think I'm using Windows 98.

sometimes with the old version of windows it is necessary that the peripheral was disconnected to install the driver.

you can also find the latest official version of the driver suporting windows 8.1 on the website of the chip manufacturer used by GQ:
h**p://www.wch-ic.com/downloads/CH341SER_ZIP.html
but keep your GMC-320 disconeted from your PC to do driver installation




I have it installed on an old Windows Vista laptop just fine. I extracted the ZIP you linked, and when I run the exe it gives me this.

So there's nothing more to do? Great...

If not, can you try to uninstall the driver and try the drivers from these links?

https://www.arduined.eu/ch340-windows-8-driver-download/

Have not tested the second one.




Neither of those work for me either, they seem like they are identical versions anyways. Uninstalling it doesn't make it work either since it seems like it never really installs it in the first place even though it says so.

What do you mean? There is only one driver posted on the downloads page and it is good for XP to Win 8.1.
