Can't connect Huawei Honor 8 to Windows 10 using USB

[AC Question]

All of a sudden it's impossible to connect my phone to a Windows 10 computer. Windows tells me "an error ocurred". Worked well last week - another security update that blocks USB-connections?

Or a bad Huawei driver in the PC. Uninstall it, then install it again.
