A customer wants to know what changes were made in the following USB stack update for QNX4: http://community.qnx.com/sf/
wiki/do/viewPage/projects.qnx4/wiki/SoftwareUpdates2010

I navigated through CVS repository and gathered the list of recent fixes that were made.  However, the logs are not very
 detailed and I could not find a PR number for each log to get more detailed information.  I'm looking for more detail 
on the changes and updates that were made to the usb2010 stack fro QNX4.

I found some more details on the release notes for the USB stack update here: http://webintra.ott.qnx.com/project_data/
QNX4/2011_Update_CD/Installation_and_Release_notes/

However, the customer wants more details than that, and wants to know how the USB stack changed at a functional level in
 order to perform an impact analysis on the changes.  Can anyone explain PR 75987 “ QMS7074-001: USB Stack Update” in 
more detail so I can provide this info to them?

Thanks,
