We don't see that "khubd timed out on ep0in len=18/64" line. So the device is okay, and it looks like your VIA controller has some sort of hardware bug. Or maybe it's a subtle incompatibility in the signalling between the MP3 player and the controller. > How to continue? David might have some ideas about investigating the bad controller in further detail. It would be nice at least for things to fail cleanly instead of hanging. However if all you care about is being able to use the MP3 device, you could simply buy an add-on PCI USB controller.
