I have connected an external monitor to my macbook pro through a thunderbolt vga adapter. The monitor has several USB ports on it and if I plug a mouse or keyboard into them, they will not work. Is there a fix for this?
Before assuming that their is a problem with your device. Some P.C's Require a manaul download of a driver. Which can be found Apple web sight.Original cable for your device is a must. If you have a cable for a camera device with the apple plug should be saficient. Sometimes additional driver to communicate with manufactures is also required for image or file output. Off brand cables are no good.
