First, we need to install loader for ATtiny 85. If you have GIT installed on your system, just ignore first command.

sudo apt install git [IF YOU DO NOT HAVE IT INSTALLED ALREADY]
git clone https://github.com/micronucleus/micronucleus
cd micronucleus/commandline/

sudo apt install libusb-dev
make CONFIG=t85_default
sudo cp micronucleus /usr/local/bin

The system does not see the new (DigiSpark) device:

$lsusb
Bus 002 Device 002: ID 090c:1000 Flash Drive
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

To fix this, we need to copy the file provided and refresh the UDEV rules:

sudo cp 49-micronucleus.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules

Ok, Raspberry recognized connected device:

$lsusb
Bus 002 Device 002: ID 090c:1000 Flash Drive
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 001 Device 004: ID 16d0:0753 MCS Digistump DigiSpark
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Additional Boards Manager URL:

• DOES NOT WORK: http://digistump.com/package_digistump_index.json could not find micronucleus
• USE THIS: https://bittit.info/package_rpi_digispark_index.json

REMEMBER: to load a new sketch you must unplug DigiSpark
