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.
