  1. I cloned the git Adafruit_nRF52_Arduino, which is not valid library to be loaded
  2. I unzipped and zipped the libraries Adafruit_LittleFS and InternalFileSystem from within (those cannot be cloned individually)
    2a) I was able to add both libraries to my sketch
  3. I tried to add the library [Adafruit_TinyUSB_Arduino @ e58ed11] in the same way
    ==> Error: The library “Adafruit_TinyUSB_Arduino-e58ed11de15e2cfbd71f1a79cf84a2372ba27e08” cannot be used.
    Library names must contain only basic letters and numbers.
    (ASCII only and no spaces, and it cannot start with a number)
  4. I added Adafruit_TinyUSB via the library manager
  5. Compilation error:
