Windows 7: Windows 7 canīt find a simple "USB keyboard" driver

Windows 7 canīt find a simple "USB keyboard" driver

Hi all,

first, sorry for my english, my spanish is pretty better.
Iīm having a weird problem, hope you guys can light me.

PC: windows 7 x64

When I was happy

2 days ago, while playing a game, a nice and cold beer dropped over my keyboard, a simple USB one, so I decided to replace it for another one.

Iīm a really simple keyboards fan, so I took another USB 15€ keyboard, a Logitech K200.

The problem

I plugged my cheap and simple new keyboard, but windows canīt find any....
Of course, Logitech doesnīt have scpecific drivers, you have to get those microsoft ones.
Well, I tried to use my old and full of beer keyboard even if some keys dosnt work, but, canīt find those drivers...same ones I guess.

What I tried before posting this

I tried all this and nothing get positive results:

-I plugged both keyboards into another computer with windows 7 x32: drivers found and both working.
-I plugged other devices: Windows finds drivers and automatically install them (pen drives and hard drives)
-Tried a system restore: I get a 0x80071a90 error and canīt get it.
-Both keyboards works into BIOS. Once Windows start up they dosnīt.

Hope someone can help me.
Thnak you

Plug in the keyboard. Click on/open Devices and Printers as shown in red box in picture below.

Then click on "Add a device" as circled in yellow below. A search window will open and it should find your keyboard and install the driver.
Hope that helps.

Thx for your help.
I already tried that, the problem is windows never can find a proper driver. I noticed that unistalling keyboard and rebooting, the keyboard works for some seconds, until I get that "canīt find any driver" message from windows.
I "disabled automatic update driver" option, but doesnīt work
I bet a dinner that my usb keyboard driver is corrupted...

Go into Device Manager and find the keyboard if listed. If it isn't listed there is no driver installed or recognized by Windows.
If you find the keyboard in Device manager with a yellow triangle next to it then the hardware is recognized but the driver is missing or damaged.

If you find the keyboard in Device Manager, highlight then right click. Then click properties. The new window should have a button to Uninstall driver or Update driver. Also sometimes their will be a button to Repair Driver. Click repair if it is listed. It probably will not be listed but sometimes it is.

If no repair option then turn this below back "On".
I "disabled automatic update driver" option, but doesnīt work
Then go to Device Manager> Keyboard> Properties as I posted above then click "Uninstall driver". This should activate "Found New Hardware Wizard" and install the driver.

Good luck. That is the only ideas I have for you.

It is kind of weird that it works in your BIOS but not in windows 7.

Hey, thx both for your support.

Thatīs exactly what I get, a yellow triangle. Iīve uninstall, reboot and "Found New Hardware Wizard" around 8 times now: never find a driver.
Thatīs why I guess driver is damaged.
Also I donīt see any repair option.

Any way to repair that driver or even download a generic one?

Durruti, try Fixio Driver Finder. It is as easy as 123.
It can determine your system, it will search for any missing drivers in your system, and install it.

Windows 7 64 bit

I have the exact same situation, and have concluded, after extensive Googling that this is actually an unacknowledged Windows issue. Windows reaches a point where it gets "confused" in attempting to identify a device, and once that occurs, that's all she wrote. PLEASE CORRECT ME IF YOU ACTUALLY KNOW BETTER. Idle speculation or theoretical solutions are not needed. I have a WIFI Mouse/KB that worked. Over time my USB drivers/ports started acting more and more erratic. I tried plugging in a Chinese SD card reader - it not only didn't work, it also "bumped" the WIFI mouse/kb driver set(more than one driver), and it's been that way despite my best efforts.

Windows 7 Ultimate x64

Same issue here.
I replaced my old USB keyboard and now windows 7 x64 says it cannot find a driver for my new keyboard.
My BIOS recognizes the keyboard very well though.
Just windows croaks. Keyboard is standard stuff so why the heck does windows suddenly show this driver problem ?
I get the yellow question mark in device mgr.
When I try a driver update windows comes back saying it could not find a driver software for my device.
I tried different USB ports as well as uninstalling the driver, let windows look for driver update on the internet as well as locally e.g. in %windir%\system32\drivers but no success.

UPDATE: My original installation of windows 7 was done with a KVM switch and a PS/2 to USB converter.
Now after I had put all the parts of my desktop into a new case I started the PC with a standalone USB keyboard.
This was when I got the strange driver issue. As a test I hooked up the KVM switch and the PS/2 converter again and the system came up with a properly recognized keyboard.
This is only a workaround though as I want my system to run with the new USB keyboard without the additional parts in between.
I still don't know why the system behaves the way it does but at least the system is useable again.
