 In "ifd_sysdep_usb_control()" after "if(count) {}", maybe you could change the 
 code so that it looks like this:
 
   if(!(ctrl.ucr_request.bRequest & UT_READ))
     return len; /* ignore STALL on write transfers */
   else
     return IFD_ERROR_COMM_ERROR;
 
 And see what happens, hence the status indicates that the data has been 
 transferred.
 
 Maybe we could compare debugging output with windows.
 
 Install the usb-snooper below, before running your application. Make sure that 
 you get the control transfers.
