Bug Description
Binary package hint: upower
Running on natty on amd64. upower 0.9.9-4.
I have a development board with a build-in generic FTDI USB Serial port adapter (USB VID:PID 0403:6001). When I plug this into my computer, upowerd grabs (opens) the serialport and thus prevent me from using the serial port.

This bug is due to a udev rule in /lib/udev/ rules.d/ 95-upower- wup.rules.
This udev rule erroneously assumes that USB VID:PID 0403:6001 is assigned to "Watts Up? Pro" from Watts Up Inc. The VID:PID is rather assiged to a FT232 USB Serial adapter chip from FTDI Inc. The FT232 is a generic electronic part which is default configured with the said VID and PID. This part is used in a lot of development boards and different kind of products. It cannot be assumed that this VID and PID belongs to the Watts Up Pro product.
