Here are the other infos :

$ id haldaemon

id hal gives a message saying that user hal does not exist

$ uname -a

I launched udevmonitor as instructed but no messages at all appeared on the screen and the file udev.log is empty

There are no udev events at all for the device, and dmesg does not have any trace of the device either, so this looks like a kernel regression.

Should I provide the dmesg trace from Breezy ?

Could be helpful. Yes, please.

That's strange but when I plug the mp3 device in the usb port in the back of the laptop it's detected and not in the port on the side. However, it worked with every port in Breezy.

This should be fixed in the next dapper update.
