I've run into similar issues on this camera myself, though I do remember that I 
could get more than 5-10 fps. I'll play around with the one I have at work on 
Monday and see if I can give you more detailed advice.

You mentioned that there was a sequence of commands that would let you set the 
exposure to an absolute value.

> $ uvcdynctrl -g 'Exposure (Absolute)'
> 100

Did you observe a change in the image when you set the exposure higher and 
lower? Setting the exposure to a very high and then a very low value should 
produce a noticabley different image. (High exposure bright image low frame 
rate, low exposure, dark image, high frame rate.) 

In the mean time, I suggest dissabling auto white-balance. You might find that 
after turning this off, you're able to set the exposure manually.

Good luck!
