It is the R UD3R, my mistake. Its funny, because the USB drive showed up in the BIOS under the "change hdd boot priority" so I would assume that Qflash would see it. I tried with and without Floppy enabled (I dont have a floppy drive). "Legacy USB Storage" and "Legacy USB Keyboard" are enabled. I ended up just creating a tiny FAT32 partition on my main drive and installed the BIOS update that way. But still, this USB thing bothers me. I almost want to buy a different thumbdrive just to ease my mind.
