Unable to mount SDHC Flash Memory Cards...

Hi folks,

I've got a troublesome problem that has been driving me nuts for a few weeks now...

I recently ran the upgrade from Fedora 10 to version 11 via the online update. Since then, everything has worked very nicely.

However, I can't get the system to recognize my USB memory cards.. I have a small card reader that has worked perfectly with earlier versions of Fedora (5, 6 and 9) I'm sure of. And this also works fine on my Windows boxes.

When I plug the card reader into the USB port, and then insert a memory card, the status light changes on the card reader to show that it detects media being inserted. However, I am not able to get the card to mount.

Usually, when I insert a USB drive, I receive a pop-up in KDE asking what operations I'd like to perform. Sorta like when you insert them into Windows. I just navigate to the folder and copy the items I want to use.

Typical USB flash drives and external hard drives work beautifully with this computer. However, the flash memory cards for my digital cameras are not doing anything.

I'm pasting the output of the fdisk -l command in the event it may help correct this problem...

The first one is if I insert an XD card out of one of my Fuji cameras... I can manually mount this volume and download the photos... However, the second example is from one of my Canons and uses the SDHC memory cards, and nothing appears in the list...

And here is the example of the SDHC card from my Canon. Unfortunately, this has become the camera I use most often and is more important to be able to retrieve photographs...
