UDEV Rules for Micronucleus boards including the Digispark.
This file must be placed at:
/etc/udev/rules.d/49-micronucleus.rules (preferred location)
or
/lib/udev/rules.d/49-micronucleus.rules (req'd on some broken systems)
After this file is copied, physically unplug and reconnect the board.
SUBSYSTEMS=="usb", ATTRS{idVendor}=="16d0", ATTRS{idProduct}=="0753", MODE:="0666" KERNEL=="ttyACM*", ATTRS{idVendor}=="16d0", ATTRS{idProduct}=="0753", MODE:="0666", ENV{ID_MM_DEVICE_IGNORE}="1"
If you share your linux system with other users, or just don't like the
idea of write permission for everybody, you can replace MODE:="0666" with
OWNER:="yourusername" to create the device owned by you, or with
GROUP:="somegroupname" and mange access using standard unix groups.
Create a file named /etc/udev/rules.d/digispark.rules with the following line in it: SUBSYSTEM=="usb", ATTR{idVendor}=="16d0", ATTR{idProduct}=="0753", MODE="0660", GROUP="dialout"
