Trackpad firmware update

[Arwen]

If you want to be a complete perfectionist perhaps the keyboard firmware should also send the created/installed information as plain-text printed into any open text field using the Super-Key & F9 (print screen) button combination for 3 seconds

How difficult could that be?

Please no. Keyboards without dedicated special keys for integrated functions should behave transparently, just translating user input to HID data. Beeing able to query the version via e.g. custom HID commands would be plenty enough.

If the trackpad is part of the keyboard USB device, then we can get firmware version with normal "lsusb" output;

Code:
