I seem to have a problem with my USBs and the UEFI. I have a Zalman card reader that plugs into the USB header on my Asrock Z68 Extreme4 motherboard. Id like my card reader plugged in AND for USB devices to work throughout the booting process. Currently, this isnt happening so I will explain below.
- When Legacy USB Support is set to Enabled or Auto, the card reader prevents my PC from posting, and it just sits there on the Asrock splash screen. If I unplug my card reader and reboot, I can boot up fine.
- When Legacy USB Support is set to Disabled, I cannot use my USB keyboard to access the UEFI (or any other option during startup such as boot menu).
- Currently, I have Legacy USB Support set to UEFI Setup Only which allows the PC to boot into Windows 7 and allows me to use my USB devices within the UEFI. However, my USB keyboard becomes unresponsive after posting and during the loading of Windows.Why is this problematic? Well lets say the PC shuts down unexpectedly, before Windows loads, a menu would appear asking me if I want to boot in safe mode, run system repair or start Windows. I cannot navigate this menu with my USB keyboard, I have to plug my PS/2 keyboard in for me to use the menu.
