Late 2012 Macbook Pro, 2.2ghz i5, 8gb ram, running OSX 10.9.3
My Novation Launchpad worked just fine 12 hours ago. I go to work, come home, plug in the device in question and I get this error:
"USB Devices Disabled: unplug the device using too much power to re-enable USB devices."
Things I tried (in order):
- unplug device from USB hub (didn't work)
- tried another cable (didn't work)
- tried another port (didn't work)
- plugged another USB device in (Novation LaunchControl) ...that works, weird...
- plugged in Launchpad (didn't work)
- restarted computer (didn't work)
- shutdown completely, wait 1-3 minutes (didn't work)
I then did some research online and saw the same problem. So then I...
- reset the PRAM/NVRAM at startup (didn't work)
- reset SMC ...which to me doesn't seem any different than just shutting it off for a while
- opened back cover...all seemed fine...nothing loose
- install some more RAM that I just purchased (didn't work)
In "SYSTEM INFORMATION" under USB I see no sign of the USB device when I plug it in, nor do I hear any confirmation 'ding' to let me know it is being recognized.
Is there any way to reset all of my USB drivers?
I have one USB device that gives me the 'USB Device Disabled' because of low power error. All other USB devices I've tried work.
