WinCE WebCam

Mini6410 WebCam Working only one
Hello,
we have a project working in Mini6410 with a logitec webcam perfectly;
using a code based on the project from codeplex (webcam.dll). We have the
problem that we are limited to only one logitec model and no other works.
we have tried to change the code for this driver but without success. 
We have also tried to use the usbdriver from Microsoft, we generate the BSP
image correctly and we compile the directshow app example correclty; but it
does not work with noone of the webcam models we have tried.(the app blocks
itself and does not show any frame, no logs available or we didnt find
them) 
We are in a stop point and we would like advice to go on: someone has got
the usbdriver working on al Mini6410?, if so we will go on in this way.
Someneone has modified the codeplex project for other webcam models
available today in the market? if so we will try again with the codeplex
modification. 
Any other suggestion?
Thanks in advance and sorry for the long post.
