Loupedeck USBデバイス「libvirtd」がUDEVルールを介してWinに渡されました。

Loupedeck USBデバイス「libvirtd」がUDEVルールを介してWinに渡されました。

私は持っていますこのコンソールQEMUで実行されているWin11にUSBに転送しようとしています。 USBデバイスに「リダイレクトする」ことが気に入らなかったので、これに対するUDEVルールを作成しました。 b/c 私はそれを持っておらず、もちろん権限もありませんでした。

ルール：

$udevadm info --attribute-walk --path=$(udevadm info --query=path --name=/dev/ttyACM0)

Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

上記の規則に従って、追加されたこのUSBをホストデバイスとして使用して、次の構成でVMを実行できます。

<hostdev mode="subsystem" type="usb" managed="yes">

    <vendor id="0x2ec2"/>
    <product id="0x0002"/>
  </source>
  <address type="usb" bus="0" port="1"/>
</hostdev>

住所がの住所と一致しますlsblk。

ls正しいデバイスを指すと、正しい権限があります（親デバイス）。

仮想マシンが起動しますが、Loupedeck デバイスはシステムに記載されていません。まったく見つかりませんでした。

私の手順を確認するために、USBペンドライブに非常に似たUDEVルールを作成し、それを正常なホストデバイスとしてインストールしました。

だから私の質問は：win11 VMでこのデバイスを使用するために何か欠けているものですか？私は何が間違っていましたか？窓から見えるようにするにはどうすればよいですか？
