I can't update PXI Hardware HID Complaint Device in windows update

The SFC scan was clear, and there's nothing seriously amiss in the background CBS.log - I'll go through the CBSPersist logs later (gotta get to work!)

There's nothing significant in the CBSPersist files - and the 80070020 error appears nowhere.

Open Device Manager - and set the View option to 'Show hidden devices'
Find any entry for the device 'PXI Hardware HID Complaint Device'
right-click on it, and select Properties. Are there any error messages associated?
repeat for each instance of the device.
Post back with the results.

post your C:\Windows\windowsupdate.log file.

This appears to be the error-sequence...

This appears to be a mouse driver.
If your mouse/trackpad is working OK, I'd say just hide the update and ignore it.

In that case, I'll try and get a hardware specialist to look over the thread and see if he can come up with something.

Look Cryptic I am no expert but what I don't understand is why the controller needs the update. It strikes me like saying my GTX 650 GPU won't work without a certain update.

The controller I have really no idea what it is so can you let us know what it actually is please so we can look at the drivers for it.
