You asked us to read and chuckle at

When I did, I read that you wanted *simple* communications between the
two computers, yet you insist on using their USB ports, which makes a
solution anthing but simple, even if you hide it by insisting on an
expensive, single-use cable: you've just bundled the complexity into
the cable hardware.

OTOH it would be far less complex to connect the computers' ethernet
ports with a length of CAT5 cable for next to no price. If the port is
broken (and it sounds as if you think it might be, but probably just
because you've never tried it) then a dongle would make sense. Either
way, communication would be conventional and simple, and you'd have a
transferrable skill just like the mid-20th century person who was
using RS232.


As for secure solutions, trying to avoid security will merely cut
you off from conventional networking tools where it's seen as
essential nowadays. (Try typing  man rcp  or  man rlogin.)
