I tried using libusb_handle_events_timeout() but had no luck with it and
then I tried to add simple timeout like this:
int ftdi_transfer_data_done(struct ftdi_transfer_control *tc)
{
int ret;
uint32_t t0 = msec_time();
while (!tc->completed)
{
ret = libusb_handle_events(tc->ftdi->usb_ctx);
if (time_diff(msec_time(), t0) > (int32_t)1000)
ret = LIBUSB_ERROR_TIMEOUT;
if (ret < 0)
{
if (ret == LIBUSB_ERROR_INTERRUPTED)
continue;
libusb_cancel_transfer(tc->transfer);
while (!tc->completed)
if (libusb_handle_events(tc->ftdi->usb_ctx) < 0)
break;
libusb_free_transfer(tc->transfer);
free (tc);
return ret;
}
}
But now this hangs in the inner while(!tc->completed) loop.
