If those don't work what about getting a USB card reader ?
any size camera memory card will work with those.

the one I have is a Sony - camera is a Olympus. no driver needed - just reads the pictures and copies then to computer.

I also saw a post on a site about some computers having a built in card reader.. does yours have any small slots on the front or anywhere - that might be it.

Usually it would be a grouping of small thin slots with a few different sizes.

Or post your computer name and model and I can look it up to see if it has them.
