Since I upgraded to Public Beta 2, I started to get these error notifications saying USB is disabled because it's using too much power.

All of the USB devices are connected through powered hub, and each devices have their own power adaptor (except for mice), so it's very unlikely it has to do with hardware. I checked system information as well, everything was fine. None of them were drawing any extra power.

Error messages usually pop up when I start or wake the machine and last about 1~2 minutes. Even if I try to close them out, it pops again till that amount of time pasts.

Here's the funny part: even if it says it has disabled a device, all USB peripherals work just fine. I'm guessing it's a glitch on Yosemite's part, but at any rate, has anyone encountered this issue before?
