网上看到一个,未必有用你自己试试 去设备管理里找到一个未识别的usb3 叫 ASMedia USB 3.0 的设备,删了,重新插拔一下。 原文 Close SteamVR. Go to device manager, universal serial bus controllers, look for ASMedia USB 3.0 and uninstall it. Unplug and plug the breakout cable and it will reinstall the drivers. Open SteamVR and it should work as expected.
