I've a YubiKey 5 NFC which I'm trying to USB pass-through to a Windows (tried 10 & 11) guest on my Proxmox VE 7.1-7 instance. The device shows up in Windows' Device Manager, but the Windows YubiKey configuration tool (YubiKey Manager) tells me that it "Failed connecting to the YubiKey. Make sure the application has the required permissions." when I attempt to configure the PIV element of the YubiKey (OTP and FIDO2 elements work). There is a YubiKey help site which says this can be resolved by running the tool as an administrator, which I've tried but to no avail.
What's odd, is that if I run an Ubuntu guest instead, the YubiKey Manager tool works. This to me suggests that USB passthrough is working fine in Proxmox.
I'm asking here as I've already asked YubiKey who told me that the device needs to be physically connected to the host and not through a hypervisor. I'm not sure if I was being fobbed off there or not, so I thought I'd ask the experts.
My question therefore are:
Has anyone successfully passed through a YubiKey to a Windows guest?
Is it possible that Linux guests would work, while Proxmox USB pass-through somehow interferes with Windows guests (even if it shows in Device Manager)? This sounds a bit far fetched to me, but I'm no expert.
