Hello,

The USB Type-A to Type-A A920-CONS-KIT-S cable, is a bust on mac and pc
laptops running linux. It DOES work for some reason, on another desktop
running linux. It also does work on same laptop running windows. Go
figure. For reference, the very excellent seeming 'Serial.app' for mac,
while very nice indeed, does not fix the problem either. It appears to
use the apple usb driver and not one of it's own as otherwise suggested.

The universal fix does seems to be the the square usb to rj45 adapter
which was also suggested by someone, so thats what is going to stay in
my tech bag. Still would love to solve the mystery tho, since we can see
on identical hardware linux doesn't work but windows does.


Thanks everyone for the suggestions.
