I use arduino UNO with ATMEGA16U2 running as FTDI chip. Furthermore According to wireshark's instructions I enabled the USB monitoring for wireshark as well.
Also over my GNU/Linux Machine the
lsusb command outputs:
Bus 001 Device 006: ID 2341:0043 Arduino SA Uno R3 (CDC ACM)
So on wireshark I selected
usbmon1 interface but in this interface also is connected the usb mouse so I get heaps of traffic so I filter it out with:
usb.addr==2341:0043 but when I do I get no traffic at all why that happens?
PS I use the sketch from this answer with
screen GNU/Linux command.
What I try to achieve is to find out the USB traffic that goes from and to the arduino in order to be able to debug easily the software that send and receives data from arduino. Therefore I want to be able to filter this traffic.
