…d logging. When an error occurs while (re)submitting a transfer buffer to LibUsb to fill with sample data, the buffer is temporarily placed in an error queue. Upon successfully submitting the next transfer buffer, we attempt to resubmit a buffer from the error queue, so that we wait until the device can accept buffers before trying to resubmit. If all transfer buffers are exhausted because they are in the error queue, then the tuner gets shutdown with an error state ... there's really no way to recover at this point.
