Module Name:

    FT2232c.h

Abstract:

    FT2232C Dual Type Devices Base Class Declaration/Definition.

Environment:

    kernel & user mode

Revision History:

    07/02/05    kra           Created.

    25/08/05    kra           Windows 2000 Professional always sets the USB buffer size to 4K ie 4096
