I recently tried to roll back the driver for a Prolific cable, but couldn't get my version of Windows 10 to allow this. The tab for "roll back driver" is grayed out. I tried to use the update driver, which I had downloaded the correct driver from Miklor, to load in. It kept saying that I had the best driver. Is there a workaround for this, now? I finally found my FTDI cable, and then didn't have any problems. But, I do have a couple of Prolific cables (no doubt fake), so, I would like to be able to use them. Thanks, if anyone has a solution.
