Every time we get any status other than

That may not be a problem, depending on what assumptions librtlsdr
makes..
Also note that a transfer with an error may also have successfully
transfered some data, but not all that was requested before the error
occurred.
2. maybe resubmit some kinds of the failed buffers
other than
LIBUSB_TRANSFER_COMPLETED, if it makes sense.
Only librtlsdr knows if it makes sense or not.
I am not a libusb guru and it's not well
documented in this part,
so I am not sure about my second point.
I know libusb well but I don't know the librtlsdr model by heart.
Naïvely I might think that once a single transfer fails then all
other transfers should be cancelled - at the very least if the
failure is because of the device disappearing.
