Permission denied for /dev/ttyUSB0 when use Docker

[chrissooo]

Hi,

My Setup:

• Raspberry Pi 4 with fresh Bookworm installation
• USB modbus Dongle on /dev/ttyUSB0
• ORNO 515

Start docker with following comman (also try privillage):

sudo docker run --privileged -p 8080:8080 --device=/dev/ttyUSB0 volkszaehler/mbmd run -a /dev/ttyUSB0 -d ORNO1p:1 --comset 8E1

After start following errors i see:

2024/09/01 10:20:49 mbmd 0.13 (fa6b574)
2024/09/01 10:20:49 config: creating RTU connection for /dev/ttyUSB0 (9600baud, 8E1)

When i download the nbmd binary fpr my pi and start it with the same Parameter for example:

./mbmd run -a /dev/ttyUSB0 -d ORNO1p:1 --comset 8E1

its work without problems.

can you help me, i make something wrong maybe?
