No problem. I repeated that second experiment: The device behind the
USB2UART just sends a "Hello World" message every three seconds. I also
figured out what the other device on that bus is and was able to mostly
silence it.
You find the binary Wireshark trace attached to this mail. It includes
the initial connection of the device.
What I could make out in the log is the following:
* Frame 41ff. (10.8s): Device connected on Port 2
* Around second 13: Running "screen /dev/ttyACM0 115200" on the host.
* Frame 131ff. (14.3s): The first "Hello World"
* Frame 174ff. (16.6s): Port suspend
--> no more communication
* Around second 52 I did:
echo "on" > /sys/bus/usb/devices/5-2/power/control
* Frame 179ff. (52.8s): Port resume
* Frame 221ff. (53.3s): "Hello World"
* More "Hello World"s every three seconds as expected
* Around second 73 I did:
echo "auto" > /sys/bus/usb/devices/5-2/power/control
* Frame 418ff. (73.7s): Port suspend
--> no more communication
* Around second 100: Disconnected device
Best regards,
