Hi Ignacio, Thank you fopr your speedy reply! The keyboard works fine with other systems, it is one of those unlisted hardware incompatibilites. The keyboard also has other problems like the CTRL key not working for multiple selections/timing out(Can be resolved by positioning the keyboard closer to the receiver than the mouse). I did start exploring the WMI route and System32_Keyboard API rather limited with regards to functional calls. I'm still looking for some code to enable/disable a hardware deive.

4. Enabling/Disabling device programatically like Device manager
Hi all, pls pardon me if this question has been asked before, if so, pls kindly enlighten me to it. Thanx. In Windwos Device Manager, you can right click on an installed device, say a USB thumbdrive and select Disable in the context menu that pops up. The USB device would appear to be unplugged from the system even though it is still plugged in. When right clicked to select Enable again, it will appear to be plugged in. I would like to achieve this effect programatically, most likely via win32 API. I've been looking around the internet for a solution, but have been going in circles. There are 2 sets of APIs which people have claimed to be able to do this, SetupDIxxx set of APIs and cfgmgr32 API. I went through them but none has any API that seems to indicate that it can be used to Disable/Enable a device. Could someone pls kindly enlighten me on how i should proceed from here? Thanx a lot, and happy year of the ox. :)

6. How to enable/disable devices in the device manager?
Hello to all the C# gurus :), I'm interested in whether it's possible to enable and/or disable devices in the device manager programmatically using C#. Anybody with some insight on this? I'm also interested in see if I can role back a driver using C#. I've seen a way to do it using unmanaged C but would love to know a way to do it using C# as well. Thanks, ks
