My I-Mac recently told me that I can only plug in 2 USB devices. Previously I plugged in 4-5 USB devices via an additional USB HUB?
Until recently I was able to plug in 4-5 USB Devices by using a powered hub. However, recently when I plugged in more than 2 usb devices, the computer gives me a message that states that some of my USB devices may not work as they are using too much power. I have not changed anything else on computer, by way of upgrades, so I have not idea what caused this problem. I need to be able to plug in at least 4 usb devices. I am using an Apple I-Mac running OS X 10.7. Any help would be appreciated.
