I am using KDE Neon and have downloaded the Arduino IDE via the Snap store. It worked well with the ESP8266 and other Arduions. But when I tried to upload a simple sketch or an example sketch to my Digispark, I get an error message. I have selected the right Board and the micronucleus programmer. I have also installed libusb. But I always get the following error message:
/home/myusername/snap/arduino/41/.arduino15/packages/digistump/tools/micronucleus/2.0a4/micronucleus: error while loading shared libraries: libusb-0.1.so.4: cannot open shared object file: No such file or directory
libusb-0.1-4
in whatever package manager KDE Neon uses. – Majenko♦ Oct 7 '20 at 19:03
