X99m Gaming 5 general USB issues
philw:
Standard x99m with a completely clearn windows 8.1 64 bit install, M2 SSD, several 3TB SATA GPT disks, UEFI/Windows Boot Manager. Standard "safe" default settings and F3 BIOS. Nothing weird, all standard/ factory defaults, all clean stuff. Disks all tested on other machines, no errors anywhere.
If I restart the system with a USB external device plugged in, to the case front ports (off F_USB30_1 and F_USB20_2), then the BIOS goes into some weird boot loop and will not start. I see the BIOS logo multiple times, but it seems that my USB keyboard etc are dead - no caps lock light etc. So I deduce that I'm losing all USB functionality. Once this happens, the only fix is to remove the device, then manually clear the BIOS memory.
There are multiple badly documented settings around these USB ports. There are multiple reports of this kind of problem on the net, but no clear fix.
So what's the deal here, please. There must be some combination of the various settings here which will make this work. Why is the BIOS not starting, and does it write a log to say that somewhere? It looks like it's trying to boot from whatever USB device I plug in the front there - I didn't tell it to do that, so why's that happening?
Any help welcome. I guess I can RMA it and swap it for an Asus, although chances are they have their own issues...
Other thoughts:
* My mouse and keyboard are connected via a USB3 hub in my monitor, would they be better directly plugged into the USB2 headers on the board? Is there something weird about the USB 3 ports?

I heard that BIOS's freeze because they can't recognize the USB devices manufacture and product ID's during booting. Some things I've tried such as Microsoft Xbox 360 controllers for PC have no problem. So I'm thinking the more popular the device is, the most likely it will boot connected.
I have a Fanatec ClubSport wheel. It's got a ON/OFF power switch. If I turn the switch ON and boot, It hangs at the Gigabyte screen. If it's OFF it boots right to the desktop just fine even with the USB cable plugged in. Then I turn it on and it works fine.
I got a bunch of USB gaming controllers that won't boot if their plugged in.
So I bought a external powered USB hub with a ON/OFF power switch and plug game controllers into that and leave it switched off while booting and turn on at the desktop.

I think that is the same issue, at root.
Looking at the Device Manager/ block diagram, there are three USB controllers, two on the x99 and one "Ranseas":
* x99 #1
* x99 #2
* Intel USB3.0 eXtensible Host Controller (XHC?)
I'm trying to figure out what is plugged into what, and what the BIOS "route this to that" thing does. At the moment I have everything in Device Manager apparently on the Intel controller, and the external drive at least does not stop every few minutes. So that is some progress. I don't think I can boot with the external drive connected, and I'm having boot issues even with it unplugged. I find it hard to believe my Samson microphone is preventing the machine booting, but perhaps it is!
If you have a hub which you power off whilst rebooting, it makes sense that the devices aren't visible, so they won't cause the issue. I may be able to use that as a work-around, if all else fails.
I'm trying to work out what precisely is causing this. I'm thinking that the BIOS has a bunch of settings, and I've a ton of interface controllers here, so some combination of this will probably work, if only I can figure out what it is.

Does anyone know precisely what the freamkin' BIOS is doing when it's refusing to boot? Back in the day the POST would actually throw up a log of what precisely it was doing at each step, so at least you could tell where it was hanging. Is there an equivalent here?

Er, that's how I know it's all hanging off the Intel controller.
The issue is more that there seems to be some "re-routing" which is going on, or at least the BIOS seems to think so. Hence what I see in the OS (which I don't need any assistance with) doesn't seem to match the block diagram.
