o The author/maintainer of the kernel USB storage code reads this
list, and can give the real answers. My non-expert advice is ...
o What is the "list of supported cameras"? For what follows, the
camera has to be a "USB storage device". When using the camera
under W*ndows, does it appear as a letter drive ("E:", "F:", etc.)
or do you need to run a special Canon program to access the images?
If the latter, gPhoto (http://www.gphoto.org/) might work.
If the former ...
o Driver matching doesn't work off the ascii name of the camera, but
instead by the vendor, product ID, and revision codes. In
/proc/bus/usb/devices there should be a "P:" line like:
P: Vendor=054c ProdID=0010 Rev= 3.22
o That's the one for my Sony camera. For what follows, you need to
look at and possibly compile the kernel from source. If you haven't
done this before, see the Kernel HOWTO and http://www.kernel.org/
o Look in the kernel source tree in drivers/usb/storage/unusual_devs.h
You'll probably have to make an additional entry like:
UNUSUAL_DEV( 0x054c, 0x0010, 0x0106, 0x0322,
"Sony",
"DSC-S30/S70/S75/505V/F505",
US_SC_SCSI, US_PR_CB, NULL,
US_FL_SINGLE_LUN | US_FL_START_STOP | US_FL_MODE_XLATE ),
o Again, this is the one for the Sony cameras. Note how the first
two hex numbers match what's in the /proc/bus/usb/devices file. The
next two are a range of revision numbers which must enclose the
actual camera's revision.
o I'm not sure about the other #define'd constants, but the above
might be a starting point. Compile/install/boot the new kernel and
see if the camera is recognized.

o When working properly, the camera is recognized when plugged into
and powered up on a running system. You don't have to reboot. A
/dev/sdX (X==some number) device file is created which can be used
to mount the camera. An entry is automatically made in /etc/fstab,
and possibly some automounter software also runs.
o Hope this helps.
