Windows 7: Windows 7 can´t find a simple "USB keyboard" driver

Hi all,

first, sorry for my english, my spanish is pretty better.
I´m 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.

I´m 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 can´t find any....
Of course, Logitech doesn´t 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, surprise....windows can´t 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 can´t get it.
-Both keyboards works into BIOS. Once Windows start up they dosn´t.

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 "can´t find any driver" message from windows.
I "disabled automatic update driver" option, but doesn´t 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".
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.

USB Driver - General Fix for Problems

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

Hey, thx both for your support.

That´s exactly what I get, a yellow triangle. I´ve uninstall, reboot and "Found New Hardware Wizard" around 8 times now: never find a driver.
That´s why I guess driver is damaged.
Also I don´t see any repair option.

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

I will try that "General fix for USB driver problems"

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.
