Yes.. I've got this mail from MS:
"...
Try the troubleshooting steps below to see if it makes a difference?
Go to the Start Menu > right-click the icon “My computer” > choose the option “Manage” > then click the option “Services and applications” > and then “Services”.
Here you can browse for a service called “HID input service” > right-click the HID input service and choose the option “Stop”
Check if you still have the same problem and then get back to us with the result.

I've tried the above troubleshooting, but there's no difference, except that, when the HID Input Service is stopped, then I can activate the HID's ind Device Management, without the CPU-Usage goes haywire... BUT, (yes of course there's a "BUT" )... when the computer is rebootet, the CPU usage goes up to 100% again.. because the HID input service has startet again automatically. Then I deactivate the HID's in Device Management, and the CPU Usage is brought down to 3-4%.
I've told MS the above thing, and I'm now awaiting their answer.
