Win7 installation missing USB drivers

I'm new to proxmox, altough using it for a year in the meanwhile to host Home Assistant and that works fine.
This week i've installed a second VM with Win7 running on it to run my KNX software ETS4 virtually. This software needs a USB Dongle to work,so i've mapped 2 USB-ports to that VM. When i wanted to install the ETS4, i couldn't see the USB-dongle. On the other USB-port i have a memory stick with the project data that i need to import when the software is installed, but that one is not visible either. In the Device Manager of Windows7 i have 2 yellow exclamation marks at Universal Serial Bus Controller and a unknown device. A little lower there Is a USB Controller installed.

Can someone help me out with this?

Thx in advance!
