Wasn't sure what you'd need the usb-cable for, now I follow.
Anyway, there are still wired remotes around?? Last time I saw one was 1981,
and
that was in the Swedish backwaters.
FYI, as for usb-extenders, my test with a 25m tp-cable did not work. You might
want to try this out first before taking into production.
