device selection : use product name instead of device name

[bizulk]

Actually we display the device name because usbmanager can return a list of them directly, device name are /dev/bus/usb/XXXX/YYYY. And these name are used for opening the connection.
But each device contains a product name simpler to recognize for user, like STM32 Com Port. Actually the developper can modify it in the device for the customer.

Instead of device name list, we should create a map of <device name, device product> so that we can display product names, and directly apply its device name when selected.
