Sierra Wireless C885 Aircard cannot see micro SD card

Hey party people,

I have a Sierra Wireless C885 Aircard. The 3G portion of it works fine. I can connect to 3G/EDGE/GPRS networks just fine. But I have tried inserting 2GB and 4GB micro SD cards in it to no avail. The memory card doesn’t get recognized in Mac and Win32 PCs. What’s wrong with it?
