USB drivers

Connecting Board and PC

Most of the current transceiver boards are equipped with a USB connector. If the USB cord is plugged into the PC, the OS will load a driver and assign a virtual serial port. Before starting the sniffer, the name of the serial port needs to be determined.

Linux:

The device names are usually:

  • /dev/ttyS[0-9] for regular RS232 serial ports,
  • /dev/ttyUSB[0-9] for FTDI and CP210x based boards and
  • /dev/ttyACM[0-9] for CDC devices like the Raven RZUSB stick.

The assigned name of a serial port can be found with the command dmesg.

$ dmesg | grep tty
usb 4-1: FTDI USB Serial Device converter now attached to ttyUSB0
cdc_acm 2-3.1:1.0: ttyACM0: USB ACM device
usb 2-3.3: cp2101 converter now attached to ttyUSB1
Windows

The name of the assigned COM port can be found with the Device Manager. A quick way to open this tool (see http://en.wikipedia.org/wiki/Device_Manager) is either to type devmgmt.msc in cmd.exe window or click: Start -> Run -> devmgmt.msc -> OK
