Trying to update AGESA in Gigabyte TRX40 designare

I’ve been plagued with USB issues since I’ve had this board and the latest UEFI only has AGESA 1.0.0.7. Updating AGESA is just about the last shot I have at resolving this so that’s what I am trying. I haven’t really found a lot of information yet on something that complex. The mod tools I’ve found so for don’t deal with updating the microcode. Also, I’m not sure how to go about getting the latest version of AGESA. I’m sure there are several other caveats I am unaware of. Can someone help point me in the right direction?

The latest UEFI is here:

Don’t have too much expectations on this…AGESA seems to be a “bitch” concerning mods as it affects several modules/code in bios.
