I just received a mpman ts300 mp3 player for Christmas. But when I try to connect it to ubuntu (10.10) through usb it doesn't seem to be recognized.
I searched for a linuxdriver but came up with nothing. I even tried installing mpman manager from the software center, but still the same problem...
Has anybody got any ideas about how to fix this?
Thank you

edit: some additional information

When I plug it in, it doesn't show up under /dev. And it is not listed in the result of 'lsusb'

This is the output of 'dmesg'
