title_body: Connect Kobo Touch to Linux PC using USB; PC not recognized by reader
upvoted_answer: Exactly  the same problem.
  Fedora 24, Kobo mini connected via micro USB cable
  
  Kobo starts charging but no sign of it on computer, no "connect" option 
  on kobo.
  
  Tried a different cable and hey presto - instant success...
  
  Sadly, I've seen this behaviour before, hence trying a different cable 
  was my first thing to try (after checking internet and finding no real 
  answers but coming across your question... )
  
  Motto is - not all cables are equal in all situations... 
  
  Hope this helps
