No - the firmware does work - it is just that the next sentence
applies, each time that the USB device is connected.

I note that that applies to the plugging in of the USB devicve, and,
not to the loaading of the television viewer (eg, MeTV, the only
television viewer application that I have found to consistently work
on both computers, on UbuntuMATE 16.04 .
When I close the application, and, later reload it, it takes a minute
or two, for the video from the television broadcast, to be displayed,
rather than the about two hours, if I have unplugged the USB device.

I have been using the USB port solely as an extension, in this case -
nothing else was plugged into any of its other sockets. The USB
extension cables that I have found for sale, are plug to plug,
requiring a socket to socket adaptor to join to another USB plug

I have just checked by viewing a bit of a stored movie, using
Kaffeine, on the i7 computer (the only one that would display video
from the device, in Kaffeine), and the sound was good and as expected.

I had thought that, after initially trying the supplied interior (to
the building) aerial, I would try it with connection to the main
household aerial, using a standard 75 ohm coaxial cable, which I have
been using for both computers. The two computers, with apparently
identical software, have different results of what they can receive
through the TV tuner device and the same aerial connection - this one
can receive pnly one network, the othe computer - the i7 computer, can
receive two networks, and, various other channels, which I assume to
be radio channels, and, if this device is not connectedinto the
particular line for the aerial, the rtelevision that would be
connected to it, can receive three of the networks, and, the
standalone (community) channel. One of the other networks (the
national (government) broadcaster network), we can only receive on one
or two days in each year, and, another television network, can be
reecived on only one received in the building - only one television.
