The Hama-MP3-Player works perfectly over the Mass-Storage Subsystem of USB.
It has no own memory, but you can use and change SD and MMC-Cards. You need
to have installed the Memory-Cards via LVM and then do the Format under
Windoze using FAT32. There is no Problem to use the so prepared Cards
under Windoze, MacOS and Linux. You can exchange Data with the provided
cable or use an externel Cardreader.
