will any usb cd drive work with a chromebook, acer book 11, plug and play, with or without external power supply? drivers needed, from where? drive should be usb 1,2,or 3? backwards compatible? any prat falls to look out for? would windows be a better choice? is a media player like VLC needed? built into the OS/ access to it? this is not mine.
CD Drives are plug and play and pretty much universal with all operating systems. You will require a power supply for most external units if your unit doesn't a power slot for that hooks directly to your PC power supply, but those are included with the purchase of your drive. A software player such a VLC will work with any drive as long as the drive works. Try narrowing your questions a bit and decide what it is you actually need or your friend needs because your questions are too global which makes it difficult to answer.
The question is now moot. She has decided to be content with not having one. She will move to windows at a later date with a model that includes one.
Chrome OS is linux. There'll be a package manager in it to download whatever burner software required
