WinUSB LibUSB

Hello togheter,

we have an Microcontroller on the USB Port, and write/read em succseed with LibUSB .
Now we try to read/write with WinUSB.

An Problem is the content of   :  WINUSB_SETUP_PACKET

LibUsb use : usb_control_msg(usb_dev_handle *dev, int requesttype, int request,int value, int index, char *bytes, int size,int timeout)
to send/recieve data , in this case WinUSB need to form out an SetupPacket:

WINUSB_SETUP_PACKET setup;
SetupPacket.RequestType = (1<<5) | 0x80; //try use type from LibUSB
SetupPacket.Request = 0;
SetupPacket.Value = 0;
SetupPacket.Index = 0;
SetupPacket.Length = sizeof(UCHAR);
WinUsb_ControlTransfer(WinusbHandle, SetupPacket, &bars, sizeof(UCHAR), &cbSent, 0);

Command ends Succsesfull! But the part got no data.

Hav any one Information to form out the setup packed correctly so we can use alternat WinUSB ?

We use it for Digispark Atiny85 Microcontrollerboard with arduino : http://digistump.com/wiki/digispark/tutorials/connecting

Thanks much for any Help
