Note that:

Your linux must have USB support (libusb, libusb-dev)

However a binary is distributed, it is strongly recommended to compile the tool from the source: in this case you will need the gnu/g++, gnu/make and libusb-dev packages installed.

t2n last version is developped in Ubuntu 22.04.4 LTS

It (probably) compiles and run on older 32 bits systems.

Setting rights for USB may be tricky. udev mechanism seems to work well in many Linuces:
- copy 72-lego.rules in "/etc/udev/rules.d" (must be root)
- warning: the ".rules" syntax depends on the udev version: you may have to fix it.
