My mouse works with the UEFI BIOS of my Asus A88x-Gamer mobo since the first time I booted my rig. After updating my BIOS from a .cap file I downloaded from Asus's website, I can boot properly and my BIOS was properly updated, but my mouse doesn't work anymore in the BIOS environment. I updated from version 0301 released as the original BIOS on 2014/07/25 to version 0603 released 2014/12/15. Here's my setup:
AMD A10-7850K
Asus A88X-GAMER
Kingston Predator 8gb (2x4Gb)
Samsung 840 Evo 128 Gb
WD Blue 1Tb
Corsair VS450
Bitfenix Shinobi Window
