My Leitner headset and the USB port on a Mac computer are not getting along
You may eventually run into USB issues when working with them so much. With a Mac computer, you may get the error message that reads "USB accessories disabled. Using too much power to enable using USB device." What should we do?
1. Unplug USB from the computer, then restart the system
2. Then restart the computer and plug the USB back in
In a few instances, this has worked, and is always worth a try.
