I tried to install the latest nRF Connect (3.1.0) on my Windows 7 dev machine and it did something to wipe out my USB setup (froze up during install of JLINK). So I had to use the latest System Restore Point to get my USB keyboard, mouse, etc to work.
But now my Nordic DK boards won't load. When I plug them in the USB, I see a "Port" show up, but the "JLINK" part of the driver doesn't show up in the "Universal Serial Bus controllers" section any more.
On this same computer, I can use my standalone J-Link debugger (the expensive kind), and I can even use it to debug my DK boards (in a limited fashion, since I was using the built-in debugger for comms too, and that's all messed up now).
These same DK boards are visible and work on a different Widows 10 laptop and Macbook (i.e. I can 'nrfjprog -f NRF52 --reset', --halt, --run and all those work). So the DK boards seem ok. I tried forcing a reload of the DK jlink firmware and that doesn't make it work on the win7 box.
Absent other good ideas to try (which are welcome), is there a way to force the complete removal of JLINK drivers from the USB subsystem of this windows 7 machine and reinstall from scratch? I've tried uninstalling JLINK itself from the programs and features" control panel (even going so far as choosing a few different versions of jlink to try) and it still doesn't work.
Edit: on the same Win7 machine, in a Mint Linux VM, the nrfjprog + jlink tools work like they are supposed to. It's only trying to use them on the Win7 host that doesn't seem to work
