I have the same in Win10, Kamper OS in the latest version 10 does not show up in device managers.
Proven classics: cable directly to the computer, reinstall RM do not help.
Reverting to version 9.0.8 restores Kemper view via windows manager and RM of course
Kemper OS 10 installed both from RM and from USB
Every time with OS10 no communication, OS9 no problem
