DevTerm CM4 64Bit

[hb121280]

I used the adapter for my CM4 module, installed the 64Bit DevTerm OS. The device boots up fine, Display is working, showing the welcome message (“Welcome to Raspberry Pi Desktop! Before you start using…”). Unfortunately neither the track ball nor the keyboard seems to be working. Anybody experienced this before? Does anybody have an idea how to proceed (apart from rebooting, already did this).
