![]() This is fairly inconvenient and not scalable at all (even if you setup an udev rule). now if you run `cat /dev/ttyACM0` or send some data to the device, you won't get any permission error This sets up an ACL in the toolbox (the root of the toolbox's GID is 100000 and the dialout GID is 18 on the host) to let the toolbox access the device run `sudo setfacl -m g:100018:rw /dev/ttyACM0` on the host. exit toolbox with `exit` to come back to the host terminal edit `/etc/group` (you must use sudo here) and append your username at the end of the dialout line To temporarly (an udev rule can make it permanent but this isn't scalable nor convenient or plug-an-play) access the /dev/ttyACM0 device **inside the toolbox**, these are the instructions (taken from the (): arduino) which are covered by the dialout group on the host. These device usually requires devices access at /dev/ttyUSB* or /dev/ttyACM* (i.e. Still, some devices might be used by developers such as dev boards or arduino-like devices. The fact is that most of them have the nobody:nobody owner, which for most of the devices is kind of normal and acceptable since they give important/critical hardware devices access. Now that all the /dev tree is bind-mounted in the toolbox, thanks to #97, all th … e devices are visible in the toolbox.

Looked around I found a guide to use ‘udev rules’ to give me permission for the device, Accessing USB serial devices in Fedora Silverblue – Just another Linux geek and I get the following error. ![]() I’ve check the permissions for the device and it’s assigned to ‘nobody:nobody’ and hence won’t allow me to access. When trying to access ‘/dev/ttyUSB0’ in the toolbox container using silverblue F36 (system release at bottom) the device fails with the following error Cannot create lockfile for /dev/ttyUSB0: Permission denied ![]()
