I just installed the Windows 10 update 1803 and after install the Moonlander2 drivers did not work.
In device manager it listed the Moonlanders but had a triangle.
BFGMiner when run says "No devices found".
I tried reinstalling them, removing them and reinstalling but to no avail. The driver Preinstaller program fails with an error.
When I try to manually install the drivers, the error says INF file invalid.

I downloaded the v6.7.5 version from the driver page and they worked!
In device manager under COM ports it no longer lists them as Moonlander2 and instead lists them as Silicon Labs CP210x USB to UART Bridge (COMx).
BFGimner now sees them

Just a tip should you run into this.
