Nobody knows. There is no centralized list. There's only a long list of patches leading from 2.6.11 to 2.6.16. You would have to go through it, select out the ones that affect the USB subsystem, and decide how significant each one is. > 2).

As best I remember, the USB support in 2.6.11 was pretty good. I doubt you will have any big difficulties using it. Eventually you _will_ have to port your work to the latest kernel. However I can understand that you don't want to do it right now. > 3). We have lot of applications which are already running on > 2.6.11.10 on the ARM board.

Why do you need to port applications? Just about anything that runs okay under 2.6.11 should run the same under 2.6.16. The kernel's interface to userspace hasn't changed much.
