Sansa Clip Sport having trouble transferring music files.

 I also suspected that might have been the case, along with the possibility of a bad USB port (so I tried three other ports, also) – but sadly neither of those appears to be the issue.

The three different cables I mentioned in the first post were:

  • the one that came with the Clip Sport

  • the one that came with my Fuze+

  • the one that came with my Kindle.

All of which do data transfer, and all of which I have used successfully with my Fuze+.

Thanks for looking, though – I appreciate it!
