Several days ago the trackpad stopped working. It started when I connected a Apple Magic Mouse for more convenient playing. When I disconnected the mouse, I realized that the trackpad stopped working. Thinking the laptop just swallowed up I restarted the system. And sure enough, the trackpad worked again… for some hours. After that I just stopped working again. Sometimes it repeaired it self to the point that I could use it, but no multi touch gestures (pinch, scroll etc) would work. I had a look in the Hardware-Manager of Windows and saw a yellow exclamation mark next to a I2C HID-Device. The error message states “A request for the HID descriptor failed”, what ever that means.
