It doesn't work in different USB ports, but will test it on another computer in a few days when i can. But it possibly could be the USB cable i think i might have got the wrong one with my mp3 player.
This kinda shows why i think that... in this picture i highlighted in red two grooves but when you look at my usb cable below it only has one groove it makes it kinda hard to fit in should it be like this? I read about this somewhere 'http://forum.s1mp3.org/viewtopic.php?t=991' which says there is little difference anyway.
Sorry for the pictures phone camera sucks...Oh and where could i find a USB cable for this if i wanted to replace it i live in NZ so DSE or something?
