I have a Sansa Fuze that has two USB devices(SD card and internal memory).

The SD card device doesn't get added.

dmesg

sdb shows  as the internal memory so the cable andUSB port seem to be working. I have no idea where to look. Any suggestions welcome. I have a Perl script that loads podcasts onto the SD in the player and it works fine on my Raspberry Pi.
