BTW more USB devices you have, or devices in general, the longer the POST will be, that is how it works as each device needs to be initialized.
Do you have another system to try that USB microphone on?
Keyboard (Steelseries Merc Stealth) and mouse (CM Storm Spawn) are both connected to the USB 2.0 ports on the back. The USB-MA Microphone Adapter is connected to the front panel USB ports (via a USB 2.0 header on the mobo; usually I leave it plugged in all the time. I also have a Koutech 3.5" panel USB flash card reader connected to another USB 2.0 mobo header. I'm only using one USB 3.0 port on the rear, connected to an external Belkin USB 2.0 hub; downstream from the hub is an Epson Perfection 1650 scanner, a Microsoft Force Feedback 2 joystick, and a Thermaltake USB to SATA hard drive dock "toaster". I have to disconnect the hub from the USB 3.0 port, in order to get into BIOS, otherwise it will hang shortly after hitting DEL; if I don't hit DEL, it will boot into Windows, whether the hub is connected or not. When booting to Windows, there is a delay before the keyboard starts working again (it works right away at POST, then quits during boot (lights go out), up until the log-in prompt + ~10s delay, while the mouse is working well before the keyboard). This build (sig rig below) replaces my Core2Quad Q9650 / GA-EP45-UD3R / G. Skill RAM, in the same case, all of the rest of the system is the same (ok, I finally took out the archaic floppy drive, and put in the included Gigabyte USB 3.0 front panel in its place, but haven't even used it yet). Everything connected to the hub works fine, without fail, in Windows. The keyboard and USB-MA always worked immediately and flawlessly on the previous motherboard, which has now been relegated to HTPC duty in a new case. Keyboard and USB-MA still work fine with the old mobo, as before, first time, every time, no re-plugging needed. I realize it takes time for the system to initialize each USB device, but see no reason the UD5H would be slower to do so than my old GA-EP45-UD3R mobo, with the same configuration (except all USB 2.0 instead of USB 3.0 on the old mobo). The keyboard isn't that big an issue for me, the delay is only a minor annoyance, but when the USB-MA fails to start, I don't notice it, until I try to use Teamspeak or Ventrilo, when they fail to find the mic. At that point, I end up having to unplug, re-plug,... until it starts working, and then go through the set-up in Ventrilo or Teamspeak again, since it messes up the config when the mic goes missing.
