Lenovo Yoga 720 usb connected device not seen

HI,

My YOGA 720 has been working fine but I bought an external plug and play CD/DVD drive and the computer does not recognize it. I tried searching this forum but could not find an answer.  I plug it into the usb port and it is not seen.

Please help

You may need additional power ( AC adaptor ) to make the CD/DVD drive work. The power from the USB may not be enough

I had similar issue, tried with 2 DVD drive, but they are not reading disks, instead there is a strange noise, but both DVD drive works with another Laptop. It is a BIOS setting issue, after set "Alway on USB" to "enable" in BIOS setting(Press F2 to enter setting after power on). Both DVD drive work immediately.
