VirtualBox 的神奇 USB Bug

Posted on

偶然開個虛擬機想要寫個啓動盤,結果發現 USB 掛載不進去。於是更新了 Guest Tools,結果還是爆炸的。但淺羽記得之前明明是可以用的,於是搜尋找到了官方的 Bug Tracker。其中提到:

As the last commenter wrote, for USB3 sticks attached to a USB3 port you need to have the xHCI controller enable in the VM config. As an alternative you can attach the stick to a USB2 port or use an USB2 extension cable to downgrade the USB3 stick to USB2.

所以解決方法是把 USB 控制器改到 xHCI。但是改了之後,Guest OS 裏面有提示沒有驅動程式,手動也安裝不上。於是找了找電腦上的 USB 2 口解決。
