[PROBLEM] Library always empty

[micke123]

I seem to have an odd problem, no music is showing up in the library list whatever I try.
I checked logs, and mpd looks like this after some testing:

Feb 23 14:58 : update: removing USB/mp3/01-3_doors_down-when_im_gone-hnh.mp3
Feb 23 15:20 : update: added USB/mp3/01-3_doors_down-when_im_gone-hnh.mp3
Feb 23 15:20 : update: added USB/mp3/19.-Eyes Of A Stranger.flac
Feb 23 15:22 : update: updating USB/mp3/01-3_doors_down-when_im_gone-hnh.mp3
Feb 23 15:22 : update: updating USB/mp3/19.-Eyes Of A Stranger.flac
Feb 23 15:22 : update: updating SDCARD/01-3_doors_down-when_im_gone-hnh.mp3
Feb 23 15:22 : update: updating SDCARD/Stereo Test/LRMonoPhase4.flac
Feb 23 15:22 : update: updating SDCARD/19.-Eyes Of A Stranger.flac

Tested to remove and insert USB many times, also tested to copy files via ssh to sdcard folder, no luck.

What have I done wrong, I can't find any settings for the USB stick.
I even tested all different releases...

Thanks in advance,
Mike
