What are you using to run the VM? Regrettably, I need a Windows install to upgrade firmware on a USB device. I'm hoping I can get it done in a VM and at least not pay them anything. I tried a little yesterday but wasn't able to install from the Win10 ISO.
I dunno what you were using but I recommend virt-viewer.
The main thing for this one is that you'll want to get a PCIe USB controller card and pass that through directly to the VM so that unplugs/replugs/device resets don't connect the device to the host machine briefly while if determines if it should pass through.
KVM/QEMU via virt-manager. I would imagine that your use case would work if you pass the USB device or the entire usb host controller through to the VM, but I'm not sure. Please check the video linked in my other comment for more information on the single GPU setup
