Trying to update my D100 using Windows 10 and the USB to Serial cable I bought from Dynon. Keep getting an error message on the Dynon support program saying “Driver error. Unable to use Comm 8”. I’ve tried all USB ports and also changed the number designated for each USB port through device manager. However, when I connect everything my D100 screen goes to the yellow screen like it is downloading but then I get the error message and it never downloads.

My experience is, that WIndows 10 does not support all serial dongles correctly anymore (chipset), I had to buy a new dongle with windows 10 in order to use it correctly. Need to dig into my history to find the one I'm using.

There has been an issue for several years with counterfeit FTDI chips out of China being used in USB to serial adapters. They seemed to work okay until Microsoft tightened Windows security, starting with Win 7 or Win 8. I suspect the earlier cables sold by Dynon may have been a casualty of this issue. A new cable might very well fix the problem.

EDIT: Apparently counterfeits are on the rise again with the ongoing supply problems with chips. It seems there's lots of counterfeits on Amazon and eBay. You should be able to get what you need here:

Make sure you get their drivers too, and load the drivers before plugging in the cable. Windows may well install the wrong drivers if you don't.
