Card readers

[forkboy1965]

I currently own a SanDisk card reader which I use to transfer my image files from my Canon 40D to my computer for processing.  I know that in part my transfer speed is based upon the USB format (1.0, 2.0, 3.0, etc.), but wonder if there is anything regarding the actual card reader that can impact transfer speed.

I ask because I now have a Canon 7D and SanDisk UDMA cards and while I cannot change my USB type connection I am willing to change to a faster card reader if such a thing exists. 

So.... am I solely at the mercy of my USB standard for transfer speed or can I increase said speed with a new and better card reader?

Thanks in advance.

I'm not aware of anything that would cause you to get a faster transfer speed just by changing card readers.  Or at least that would be worth the cost of switching between USB 2.0-type card readers.
