I want to use “UsbBuildVendorRequest” to control a USB camera chip register…
but I don’t know how to get this fuction’s parameter…
IN DDK…
VOID
UsbBuildVendorRequest(
IN PURB Urb,
IN USHORT Function,
IN USHORT Length,
IN ULONG TransferFlags,
IN UCHAR ReservedBits,
IN UCHAR Request,
IN USHORT Value,
IN USHORT Index,
IN PVOID TransferBuffer OPTIONAL,
IN PMDL TransferBufferMDL OPTIONAL,
IN ULONG TransferBufferLength,
IN PURB Link OPTIONAL,
);
Actually, I don’t know how to get “Request”,“Value” among those parameters.
Requet and Value indicate the device so I must know these to control device…
But I could not find it in Data Sheet…
