BRIO 4Kストリームウェブカメラは、windows-10-proマシンでは高解像度を報告しませんが、windows-10-homeマシンではすべて正常に動作します。
この問題をトラブルシューティングする方法はありますか?

BRIO 4Kストリームウェブカメラは、UHD解像度を報告するためにUSB3.1ポートを必要とします。
PEX-U31-01 Gembird 2-port USB 3.1 PCI-Express add-on card
をテストしました
SATA電源ケーブルを接続することを忘れないでください
PEX-U31-01
カードに接続すると、カメラはUHDモードを報告します。

カードを使用した1080p以上の解像度ではキャプチャが機能しないことです。 Logitech Capture
