Really?
Microchip INF files for CDC don't follow these MS guideline of INF, even on the latest (v2.7) version of MCHPFSUSB stack (v2010-04-28).
1) Don't write LayoutFile on [Version] section. 2) Don't specify usbser.sys directly for CopyFiles Instead, include mdmcpq.inf AND refer to FakeModemCopyFileSection
I've pointed out it on this topic of Microchip forum. " href= "http://msdn.microsoft.com/en-us/library/ff547502">msdn.microsoft.com/.../ff547502(VS.85).aspx LayoutFile Note This entry is not supported in Windows Vista and later versions of Windows.
2) How to use or to reference the Usbser.sys driver from universal serial bus (USB) modem .inf files support.microsoft.com/.../837637
