sceeter32 Posted March 4, 2009 Report Share Posted March 4, 2009 Hello everyone! I have a question. As everyone know the keyboard for the iMac has 2 usb ports, and is wonder why every time I plug my iPod Touch on one side and then plug my thumb drive on the other side I get a warning saying something like usb power is low, please unplug one of them. I tried to plug both of them in the back and can run both of them fine with no warnings. Why just the keyboard?Thanks Quote Link to post Share on other sites
isteve Posted March 4, 2009 Report Share Posted March 4, 2009 Each USB port has a limited amount of power. There is usually enough power to power the apple keyboard the mouse (usually plugged into the keyboard) and one other device like a thumb drive. Sometimes ipods that are low on charge will by themselves be two much for the keyboard. The rule use to be one powered device per port most times you can get away with a few lowpowered devices. You can get powered usb hubs that will run multiple devices. Quote Link to post Share on other sites
