Please try turning on the usb-storage verbose debugging option in the kernel configuration. Then post the debugging messages that show up in the log when you plug in the player. (You may need to edit /etc/syslog.conf to tell syslogd that it should store debug-level kernel messages. Or you might be able to use dmesg instead of the log.)
