買了一台LITEON EBAU108 外接光碟機，它後面只有一個插孔，一條線連接USB孔!
但很奇怪...插上USB光碟機沒反應! !
但我用另一台外接光碟機，是兩條USB線，一條電源一條不知道是什麼就正常，都有亮燈!
確定我USB孔是好的! ! 我也用筆電測試一樣的情況! !
請問有人知道為什麼嗎? ? 光碟機壞掉????

您是用什麼系統?
Windows可以試試看下面方法
Reinstall a device that appears in Device Manager with an exclamation mark:
Open Device Manager and plug in the drive.
Locate "DVD/CD-ROM Drives". Click on the “>” next to it.
Right-click on the device with the exclamation mark next to it and click ‘Disable Device’ to turn it off.
Right-click on it again and click ‘Properties’.
In the window that pops up, click on the ‘Driver’ tab.
Click on ‘Uninstall Device’, and then follow the instructions carefully to ensure that you uninstall the drivers (IMPORTANT: you may need to click on a checkbox to confirm that you want to uninstall the drivers).
Unplug the external drive from the USB ports.
Shut down your computer (be sure to shut it down fully, don’t just restart it).
With the computer powered off, plug in the external drive to the USB ports.
