Refined serial port selection.

Browse Source 
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.
