Hi,

Model: ASUS Rampage IV Extreme
BIOS: 0604 x64

Problem(s):
1. I have only attached one USB Keyboard (NO PS/2 Keyboard) to the motherboard. When I go to BIOS under Advance -> USB Configuration, I see that my motherboard detect 2 USB Keyboards. When I disconnect that keyboard, motherboard detects 1 keyboard (No keyboard attached to it). Can someone please help me on how to fix this problem?

What I have tried so far:
a. I cleared the CMOS (Technician from ASUS told me) by basically removing battery from motherboard, wait 1 minute, while waiting, hold power bottom to clear all charges and then put everything back on (Didn't work).

b. Flash bios to newer version, 1101 (That didn't work).

c. Flashback (Tools -> Flashback) the BIOS (0604) (That didn't work).

Thanks
Mani

Is there any contaminate in one of the USB ports, a bit of waste matter that might be fooling the USB into thinking there is something connected?

Have a good visual inspection and check if all clear.
To help us help you - please provide as much information about your system and the problem as possible.

its just a misreport (some USB devices are picked up as keyboard). The system should be working fine regardless.


You can update to a later UEFI also.

Thank you guys for the reply.

I checked all the USB port, I didn't detect anything. Is there any way that I can fix the misreport? I also update my BIOS to ver. 1101 and I still see the same thing (Did FlashBack after upgrading and that didn't work either).

Beside that motherboard works fine (When I called ASUS, one the agent told me that my motherboard is defected and I should send it to them to fix it, is true?).


Why I'm Concern:
My Motherboard reported everything fine until 3 weeks ago that I had to change my keyboard (Some of the keys wasn't working and I got the replacement for it). After connecting the new keyboard (Same brand of keyboard , same USB port as before), I see that my Motherboard reports "2 Keyboards, 1 Mouse, 2 Hubs".

I get the same misreport as well. I see it on my initial boot up screen as well. But I have experienced no negative affects from it and simply ignore it.

Thanks for the reply.

Another thing that worries me is the keylogger. Maybe because of that it shows two keyboards. I might be wrong. I don't have much experience in computer.

Me too, this only appears to show IF the keyboard is attached through USB, adding the converter and pluging it into the PS2 port and it informs there are NO keyboards attached!!! :eek: Yet here I am tapping on one 🙂

I think at end of the day, it's essentially a non-issue caused by to a bug in the UEFI BIOS.

Glad that I'm not the only one here experiencing this problem. If it's a bug hopefully they fix it in the next release of BIOS.

Another thing that I notice is "Windows Boot Manager" under Boot menu. I installed windows 7 Pro x64 and Uninstall it by zero fill the hard drive. I still see "Windows Boot Manager" in my BIOS. Does anyone knows on how to delete it from boot menu.

I'm thinking that when BIOS detects something it saves it and on the next restart it never checks to see if it is still exist. I might be wrong.

Mine also does this. No noticeable problems because of it.
Simply cosmetic.

It's just a bug report, it will require a large amount of time to 'fix' (depends on how devices are recognised) and because the boards are working fine it is not a high-priority for us at the moment. High priority items are those that are causing gross incompatibility and non-function.
