USB com port assignment mixed after every reboot. Anyway to fix them?

I’m using 3 Digi AnywhereUSB/2 to deploy a few home-automation transceivers around my site, controlled by a HomeSeer software that runs on a Windows 8.1 machine.

These are the USB devices:

  • 3x RFXCOM RFXtrx433 transceivers
  • 2x UZB stick

The RFXtrx and UZB sticks are usb-to-serial converter devices, so they’re each assigned COM ports and I map the location to the correct device in the HomeSeer software.

The problem that I’m facing is that the COM assignments are not static. Everytime the system is rebooted, there’s a chance that the UZB sticks are swapped, and that would completely mess with automation events and device coverage.

Is there anyway to lock the UZB sticks to a fixed COM port and have them assigned to the right one, in the event of a computer restart?

Thanks in advance


This question is best suited for the vendors of the USB devices in question, as the AnywhereUSB does not control COM port assignments.
