GA-Z87N-WIFI, WinPE, have to boot twice to get mouse

GA-Z87N-WIFI, WinPE, have to boot twice to get mouse.

Happens with Acronis and EaseUS WinPE.

I have a genuine MS wired mouse (USB), and a Logitech M510 Wireless (USB) mouse.  I get neither on first boot. I get both on second boot. Always.

I get mouse working on first boot on my laptop (2yr old Lenovo V570).

I am guessing it's the BIOS, but any ideas as to what to change?  I am running Win7 Pro x64 SP1 current and have set BIOS to "other OS" (I set  OS TYPE to Win8 so I could set CSM Support to "never" and then set OS TYPE back to Other OS)

EDIT: I had EaseUS todo backup workstation 6.1 write WinPE to a CD and get the same behavior - no mouse on first boot, mouse on second boot.  UEFI doesn't like WinPE.

Thanks for your time.

The board came with the latest BIOS - F4.  It is a rev 1.1 mobo, which is the latest.

anyone?

I can press the hardware reset button one sec after telling it to boot the first time, press F12, tell it to boot again and let it go through and it works fine. This is a BIOS UEFI problem.  Fix please!  It won't allow a booted system to see HID until second consecutive boot.

EDIT
I set
BIOS Features (which is set to Other OS)
   Windows 8 features
     Boot mode selection  to "legacy only, and anything else I could see to legacy, power cycled the machine and it worked the first time ONCE, then reverted to working only on the second time.  Isn't UEFI just so wonderful...

Problem solved by replacing mobo (same model) and getting a PS2 mouse.  Now I get mouse the first time I boot to WinPE on USB flash drive, though sometimes it's the PS2 mouse and sometimes it's the wireless USB mouse.  Go figure.  Does anyone really know what a UEFI BIOS is really actually doing?
