I figured I'd bump this because I'm having a similar issue.
I've been using a Silicon Labs Zigbee/Z-Wave hub for the past 5 years or so. Running HA on Synology VM. This week, my Zigbee hub stopped connecting. Z-Wave was still running just fine.

An lsusb command on the Synology shows the USB is still there:
The VM also still has access to it:
However, like the OP, I do not have a device path of ttyACM0 or ttyUSB0. Just these:
