"Usb hub power exceeded" & keyboard won't work; but it DID work fine..
I have a Razer mouse, wireless Corsair Vengeance headset, and a CM Storm Trigger keyboard plugged into the back usb ports of my computer (desktop). Yesterday morning everything was working great. I also had a couple of random charging cables in use from the front usb ports of my comp - more than enough power.
I added a CD drive (didn't have one before) and also moved my desktop (it took a short drive in the car). (I did not test it between installing the CD drive and moving it).
Now, set up at its new place I plugged everything back in last night and everything worked except for my keyboard. Other devices work in the ports that it did not work in, so it can't be the motherboard/usb ports themselves... right?
Everytime I plug the keyboard in (USB 2 or 3) it works for between 0.5s and 2 min before throwing the "USB hub power exceeded" error. But NOTHING has changed except for the addition of a CD-drive! Could the addition of the CD drive be causing enough of a power drain that it cannot keep up with the keyboard?
Anyone know how I can fix this? I'm going to get an external power source (its optional, and I never needed one before) for the keyboard after work today as I do not feel like fiddling with my comp today and just want it to work - but this is seriously weird/a pain. It DID have enough power for everything... could something have been knocked loose while installing the CD-drive perhaps thats now not giving enough consistant power...?
Do I need a new power supply...?
Anyone have any idea whats going on?
