Anyone use a Rio Cali Sport with CentOS 4.2?

My wife does and here's the problem. It automatically mounts the flash 
memory of the player. But it doesn't mount the SD card slot. I used Ubuntu 
5.10 recently and it mounted both of them. Both as separate USB sticks. 
How do I get CentOS to do the same thing? Or can it not discern that two 
USB flash devices are plugged in?
