not sure what this device is or what driver I would need to fix this. I have all the required drivers for this model and have installed them all one by one with restarts after each one. I have gone through and checked if there are any that I have missed and all are accounted for. any help will be greatly appreciated, feel free to ask any additional questions of me.

CF-29LQQ27BM, I installed the hkeyapp driver, then the hkeyset, then the hotkey driver. I still cannot use the FN key and as I stated above don't know what that"unkown device is. also the touchscreen worked great before the fresh install and now it does not work. there is no option to calibrate it under Mouse pointer options.

You have to update in device manager, point to UTIL in programs on drive C
The mouse driver and the hotkey driver do not install themselves
It is all stated in the CF-29 FAQ, i suggest to read that first

 For what ever reason you'll need to go to the device manager and tell it to reinstall the hotkey driver. Specify the location as where it unzipped or installed when you clicked the setup icon. Once it locates the driver, the unknown will be come known...
     
Had the same problem myself... - 
 
 That is the only right way to install the hotkey driver for this unit and other toughbook and also the touchscreen diver for 28, 29 m34 and etc but other like cf-73 has dif.. coz it use a usb not serial for touchscreen.

thank you all for the responses to my posting. I will give it all a try when I have a chance. now I also have a CF-30C3P26BM and this one under Device management has a yellow exclamation mark for SMBUS Controller. can anyone guide me on how to fix that please. I have searched on the forum and cannot find the information I need.
