The Update Rollup didnt really do it for me.. :-(
After experimenting with the various registry entries in the
CriticalDeviceDatabase and driver Start values, it appears that I MUST
set the usbccgp Start value to 0 (i.e., Boot start). Are there any
side effects of doing so .. ? I am wondering if the usbccgp.sys
depends on the existence of any other driver components ... Does
anyone know ?
It appears that I also need the same changes in the system hive after
the FBA runs..otherwise I get the Stop 7B error again. How do I make
changes such that it can be used for the first boot and then persists
after the fba has also run ?
Thanks
