i’m using an onlykey duo on qubes os, but it’s poorly supported. for example, i can’t pass the usb device to other qubes. i get the following dmegs when i try:

```auto
[2466.818614] vhci_hcd vhci_hcd.0: pdev(0) rhport(0) sockfd(0)
[2466.818619] vhci_hcd vhci_hcd.0: devid(262147) speed(2) speed_str(full-speed)
[2466.818659] vhci_hcd vhci_hcd.0: Device attached

[2472.181708] usb 1-1: enqueue for inactive port 0
[2472.181710] usb 1-1: unable to read config index 0 descriptor/start: -19
[2472.243739] vhci_hcd: vhci_device speed not set

```

i’m trying to pass the device for two use cases:

- to give it to the vault vm that runs keepassxc, so that it can detect it as an available security key
- because i’d like to try to write some tooling for onlykey, but my dev qube needs to see the onlykey for me to do that
