Phone Modem integration locks up during installation

I purchased a StarTech USB56KEMH2 modem off eBay to move my caller ID automations from Homeseer to HA. When I attempt to add the Phone Modem integration to HA, the process finds the modem.

However, once I press “Submit”, the integration installation never ends and HA becomes unresponsive. The only way to get HA running again is to reboot either the VM or the PC.

I have HA running in VirtualBox on a Win11 mini PC and have enabled the USB passthrough to the HA VM. I have tried moving the modem to another PC and it shows up in device manager as working properly.

Any ideas on what I might try to get this device to work with HA?
