Laptop not mounting SD chip

I have a Dell Vostro 1015 that has been happily running Mageia 2
since release. This laptop, as do many others, features an SD
slot. Plug in the SD chip and Mageia 2 recognizes ths chip and
offers to open Dolphin displaying the data contained. This has
been working successfully since the Mageia 2 install.
For testing I have replaced Mageia 2 with M3B1. M3B1 does not
recongnize the plugged in SD chip. Leaving M3B1 installed on
the HD I booted an M2 Live-CD and sure enough the Live-CD
recognizes the plugged in SD chip.
Both OS's recongnize, and open in Dolphin, a memory device plugged
into the USB port.
What report should I be posting here?
