Refined serial port selection.

So far up to two ports with the substring "usbserial" in their name were used. This was pretty platform specific and didn't allow to use non-USB ports at all.

Now if the -p option is given its value is used as substring as "usbserial" was used before. However if no -p option is given than up to two USB-backed ports are used.
