Arrrgh. I am almost ripping my hair out over this one:
I have a USB JTAG device that interfaces with my Windows 10 PC to program certain development boards at work. On Monday, I was using it just fine all morning, and then I paused for lunch. When I came back I had the delight of watching Windows "reclassify" the device into a pair of serial ports. It did this all on its own and I have no idea why it would just suddenly do this, but now the JTAG device no longer works, and I am unable to put the drivers in for the JTAGger because Windows is telling me the best (and totally incompatible) driver is already loaded for this device.
I can't get rid of the new driver.
This is what I have tried:
1. Removed the new driver and tried a re-install of the proper driver ("best driver is already loaded" it says)
2. Edited the registry to take out as many of the new driver entries as I could find.
3. Uninstalled all Windows updates for the last month
4. Moved the new driver out of Windows/System32/drivers, but the PC still finds the wrong driver
This is like a cheesy guy that I cannot get away from. This driver just keeps following me around and it re-installs itself every time I connect the JTAG device to USB. How do I get rid of it and be able to put the right one in? I am puzzled.
And this is not the only computer in the office that this has suddenly happened to. All since Monday/Tuesday.
Help. Please?
