Having trouble uploading

I just got a new MacBook, and I'm trying to upload images from my Canon Rebel Xsi, I also have an Optex milti card reader. My problem is that when I plug either into my mac, it doesn't respond at all. I'm wondering if anyone might be able to help me with this? Even going into iPhoto and trying to import the photos doesn't work. I'm just confused :S The weirdest part is, when I went to upload photos from a Fujifilm camera I have, iPhoto recognized that it was plugged in right away. Any help would be GREATLY appreciated.

Probably won't be able to do any testing until late tomorrow. Just got my XSi. Have not had any problems importing into Aperture using a 8GB SDHC card and reader. Have not connected the camera to the computer.

If you're using an SDHC card, some of the older readers will not work with them.

As i recall there are 2 apps that have a check box to open automatically when camera connected - so i would check out Prefs for Image Capture and iPhoto to see how they are set up. Not sure if that will help, but if i cross my fingers i can't click the mouse button.

If you are using a SDHC card I don't think your reader will support it. The standard SD cards are the identical size of SDHC but designed differently and are only recognized by SDHC readers. I picked up a new SanDisk MobileMate SD+ for about $12 at Best Buy just for SDHC. My old muliti reader wouldn't read SDHC cards either.
