"USB Super Drive: My U SB SuperDrive worked fine with my previous MacBook but I can't get it to work on my new macbookPro: I have bought a Multifunction USB Hub but it keeps telling me that I need power to the usb but I can't find an adaptor that will allow me to provide power. Can anyone help me please?"

What to Try:
Troubleshooting High-End External Power:
What happens when you restart your Mac with this plugged in? Does it then work? If so, then things needed to re-sync.
Boot in Safe Mode [Hold Down: the shift key] upon boot. In Safe Mode, login items do not open at login, and corrupted files are reset. So, boot into it, and see if it then works.
Try creating a new Administrator (for troubleshooting purposes). See if it then works. If it does work, then it is likely something misconfigured in the current user.
- External Powered USB Hub:
If you are connecting high powered devices, then use an external-powered USB hub. See this on Apple: Belkin USB 3.0 4-Port Hub + USB-C Cable - Apple
