I have a Genius USB Keyboard, model KB-M220.

The guide says that it works in Windows 7.

I have Windows 7 Professional 64 bits and the keyboard doesn't work here.

This is how it appears in device manager:

If anyone can help, I would be grateful

Did you install the driver? – Dave Dec 18 '12 at 12:46
Thanks for your response. I don't find any driver avaiable in the net for W7 64 bits. I've searched a lot of time.... but nothing :( Apparently, this keyboard doesn't need any driver :S – JV Lobo Dec 18 '12 at 12:50
It's a common port of my laptop (compaq presario cq60). It isn't USB 3.0 – JV Lobo Dec 18 '12 at 13:04
Device Manager detect it,as "USB Keyboard", but it can't find a driver, neither at Internet neithar in my computer. – JV Lobo Dec 18 '12 at 13:11
Under Keyboards appear: "Standard PS/2 Keyboard". And Under Other devices appear "USB Keyboard" like a device without driver. I show you in this screenshot: link – JV Lobo Dec 18 '12 at 13:21

As per our comments, try the keyboard in the BIOS to prove if it is a driver issue or not. Since it works in the BIOS, we can return to the drives for Windows.

In device manager, expand "Universal Serial Bus controllers", right click on the "Host Controller" and Uninstall.

Failing that, the driver can be downloaded here . When downloaded, open Device manager, find the USB keyboard (with the yellow exclamation mark), right click, properties. Open 2nd tab called Driver, and click Update driver. Then, click on Browse my computer for driver software.

Click browse and select the new .dll file.

I downloaded the driver that you say me. Later, in the Device Manage, double click in "USB Keyboard" -> "Driver Update" -> "Search Software Controller in this computer" and I select the folder that I downloaded previously. And now, the window show: "Windows can't install the USB Keyboard" - "Windows can't find the controller software for this device" :S – JV Lobo Dec 18 '12 at 14:55
@user1522176 - No, you need to select Browse my computer (see my updated post) – Dave Dec 18 '12 at 15:07
Yes, is the same that I did. It just that in my computer, is in spanish, and the button is: "Search my computer for driver software" - "Search and install driver software manually". I did this, and when I selected the folder which contain the .dll file, Windows says me that it can't install the USB Keyboard :( I don't know why – JV Lobo Dec 18 '12 at 15:18
In that case, I'm sorry, I would email Genius and see if they reply. – Dave Dec 18 '12 at 15:21
Oh :(, I understand it. Thanks a lot for your help. – JV Lobo Dec 18 '12 at 15:22
