tty2usb
Find the USB address of a USB-based serial port
Serial ports are a classic way for computers and peripheral devices to communicate. Originally modems, printers and laboratory equiptment had serial ports. The serial ports were hardware chips with known addresses.
Modern computers and devices often use USB to emulate serial communications. This works well, except the device has a serial address (e.g. ttyUSB0) and a USB address.
tty2usb is a utility that probe system information to display the link between USB and serial addresses.
