If you have electric soldering iron you can do it

The connection from pin1 (rightmost in this pic) to pin2 which is ID signal, i.e. the red line next to GND label, is incorrect. Pin2 should NOT get connected hard to GND. Though it doesn't do too much of a harm, it might cause conflicts with future versions of e.g h-e-n hostmode-pkg

Rationale: ID (pin2) is meant to detect insertion of A type plugs into (usually) AB-micro-receptacles. It signals to device to act as a USB host. It doesn't work OOTB on N900, but future H-E-N might actually look at it.
