Print serial port path/name in output of ola_dev_info

[sdbbs]

In response to comment in #2000 :

Btw, is it possible to somehow get the corresponding device path of ENTTEC (for me, /det/ttyUSB0) from OLA? I know ola_dev_info output something like "Device 2: Enttec Usb Pro Device .... port 0, OUT, patched to universe 1, RDM supported", but there is no /dev/ttyUSB0 device path there (I have to look for startup messages in syslog like "olad: plugins/usbpro/WidgetDetectorThread.cpp:215: Found potential USB Serial device at /dev/ttyUSB0" to find the device path).

Not if you can't currently see it on ola_dev_info, and if you could it would probably still be down to parsing a string that might change. Do you want to open a new issue for this as maybe we should extend our device info stuff to have some sort of path (be that on the device or as an IP) as a specific separate piece of info:

It would be great if the OLA device info could be expanded to also print this information.

In support of this, I'd like to note that I've used the https://sigrok.org/gitweb/?p=libserialport.git;a=tree in an executable, and the command sp_get_port_name(port) returns /dev/ttyUSB0 on Raspberry Pi, and COMx on Windows.
