My MBA will not allow me to use both usb ports at the same time. as soon as i plug the second in the first is disabled. trying to use a modem and printer.
What kind of peripherals are you connecting? Sometimes if an external device is drawing too much power, then it will shut down one of the USB ports. Make a test connecting two usb flash drives, it should work ok.
THank you, I have tested with two flash drives and they work so the power issue must be correct. Frustrating!
Yes, it is, you should also check if your peripheral has 2 USB connectors, then you must use both of them.
