After installing Windows 10 ten out of the 12 usb ports stopped working. I plugged in a flash drive and while it doesn't work in Windows it shows up inside the BIOS.
Specs
Asus Z87I Pro
I5 4460
8Gb ram
Silverstone SFX-L 500W
GTX 960
These are the only two working.
-EDIT-
Fixed by reinstalling Windows. Must have been a software glitch.
