Module Name:
USB_DFW.H
Abstract:
Extracted structures from USBDI.H to allow apps to use the struct alignment of their
choice for the common device framework structures. Due to the problems w/ byte alignment,
apps that use the USBDI.H file cannot always end up with the same alignment if all the
proper env variables aren't set. So, this file is created to pull o ut the interesting
stuff and allow apps to use it.
BUGBUG :
Need to fix this somehow so that we can import USBDI.H directly. The trick is to
figure out which vars must be set properly to get the #include <PSHPACK1.H> to do the right things
because now even though that #include is in USBDI.H, it isn't causing the right things to happen
because of incorrectly set env vars.
