cannot connect to digital camera via USB

Hi LIst;

I just bought a new Nikon D300 digital SLR - it uses a 4G compact flash card.  
I'm running Fedora 7 & KDE. When I plug it it I get the dialog asking me what 
to do, I select 'open in new window' and a new konqueror window opens pointed 
to 'system:/media/camera' but no files show up. Then I get a opo-up dialog 
that says :

"Could not read file Could not claim the USB device"


dmesg shows this:

I'm not sure how to go about debugging this or even what device name I would 
use to try a manual mount command. Any thoughts?

Also, would a compact flash reader be a better solution with Linux - my old 
camera used SD cards and in general SD readers worked fine with my Linux 
machines.


Thanks in advance ...
