Exception: No Meshtastic devices detected

Trying to run meshtastic on a Raspberrypi connected to a T-beam 1.1 via USB, unfortunately I get error message “Exception: No Meshtastic devices detected” when executing the command “meshtastic --debug”. Using the comman dmesg it seems that the device is found:

[446233.583211] usb 1-1.4: new full-speed USB device number 4 using xhci_hcd
[446233.720531] usb 1-1.4: New USB device found, idVendor=10c4, idProduct=ea60, bcdDevice= 1.00
[446233.720547] usb 1-1.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[446233.720561] usb 1-1.4: Product: CP2104 USB to UART Bridge Controller
[446233.720574] usb 1-1.4: Manufacturer: Silicon Labs
[446233.720586] usb 1-1.4: SerialNumber: 0202AE59

Any ideas?

That means it couldn’t find the serial port your device is on.

Try again with:

./meshtastic --device /dev/somedevice

where “somedevice” your serial port.

Also unless that log is missing a few lines, it seems something isn’t quite right with your serial port setup on your rasberry pi (is hotplug not installed?).

There should be two more lines that look like:

[1125712.497585] cp210x 3-4.2:1.0: cp210x converter detected
[1125712.499257] usb 3-4.2: cp210x converter now attached to ttyUSB0

Thanks for your reply. After restart of the raspberrypi the hotplug is working and meshtastic finds the tyyUSB0.
