		bytes is just a pointer so could be anything.

		I've compiled a version of the library which traps a negative size, =
hopefully it won't get stripped on the way to you.

		Hi again,
		=20
		I have traced the -ENOMEM down to windows.c - usb_submit_async()=20
		=20
		  if(!DeviceIoControl(c->dev->impl_info,=20
		                      c->control_code,=20
		                      &c->req, sizeof(libusb_request),=20
		                      c->bytes,=20
		                      c->size, &ret, &c->ol))
		    {
		      if(GetLastError() !=3D ERROR_IO_PENDING)
		        {
		          USB_ERROR_STR(-win_error_to_errno(), "usb_submit_async: "
		                        "error: %s", win_error_to_string());
		        }
		    }
	=09
		one of the parameters (maybe c->size or c->bytes ...) must be negative =
or too big.
		=20
		Btw. does anybody have a working project or workspace for Visual =
Studio that can rebuild the .dll ?
