When I try to upgrade my mEDBG firmware, the application restarts the board into DFU mode, but Windows doesn't load the ATm32U4DFU driver.
I looked in my Atmel Studio folder for the driver, but I don't see any inf files for anything other than the Jungo stuff, which I gather isn't the right driver for this device.
I tried downloading driver-atmel-installer-x64-7.0.305.msi and driver-atmel-bundle-7.0.666.exe and AtmelStudioUSB-7.0.31.exe, and driver-libusb0-installer-x64-7.0.305.msi and none of them work -- the exe files fail and rollback, and the MSI files either appear to do nothing, or they produce the error message "The specified account already exists"
Which drivers should I use for ATm32U4DFU?
I'm on Windows 10 build 14291
