No, not sure, but I am not clear on whether this is a kernel function or
a cardreader function.

I had tried that without success - and got a single message (nothing was repeating):

usb 1-6: new high speed USB device using ehci_hcd and address 4
usb 1-6: configuration #1 chosen from 1 choice
usb 1-6: New USB device found, idVendor=04a9, idProduct=31ea
usb 1-6: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-6: Product: Canon Digital Camera
usb 1-6: Manufacturer: Canon Inc.

I took that to mean that the camera (Canon EOS T2i, relatively new)
is not supported by the kernel. Digikam probably has a driver for it, though.

I'm afraid that your thought of the reader not supporting SDHC memory maybe 
right on target. I may be able to find a camera driver and use that instead.
