USB Passthrough on KVM (Windows)

Looking through the docs... I see that only KVM can use the usb passthrough option, and I understand that. However, the windows kvm do not see the drive assigned to it.

Are the USB Passthroughs no supported on Windows KVM?

Thanks

That's weird.  I have a usb dvd drive attached to my antsle one XD that I'm passing through to my Windows 10 KVM.

If it's a USB drive, does it appear in the Disk Manager (Computer Management -> Disk Management)?

No sir it does not.  I can assign it to the antlet in antMan, however it is not found anywhere in Windows 7
