I was on my computer when I got a BSOD on Windows 8 -- It restarted and when it's booting my keyboard lights up, and my mouse. Once I get to the welcome screen both turn off and stop working. I've enabled USB Legacy support in the BIOS and I've also tried every one of my USB ports. I do not have a PS2 port so that is not an option. I've tried doing Shift + F8 during boot to get to the recovery console and no luck there either. This is really frustrating.

I occasionally have the same problem - no k/b or mouse on first Win8 screen. For me the solution is to close down the PC by holding in the on/off switch on the system unit until the PC is fully off, then reboot.
Does this 'solution' suggest to anyone what the cause might be, and thus a more permanent solution?
I also experience this problem after weeks of using Windows 8. I disabled 'USB Legacy Support' in the BIOS and everything works fine. Thanks for solution Eric. [ I will also see with time... ]
Just and update. It is now over two months and the issue has not reoccurred.
The only known permanent solution is to create a scheduled task that reboot the 2 USB controllers that freeze at windows startup uscing DevCon.exe.
This way i solved (and deactivating USB Legacy Support didn't work for me)
How do you schedule a task when the keyboard and mouse are not being recognised ?
Diasbling the USB devices and enabling them did not work for me.
