The problem is not that it's too complicated to operate. The problem
is that having a human astronaut interact with any piece of equipment
has to be scheduled far in advance, through the PAO if I recall
correctly. Whereas a system set up to operate autonomously or accept
ground commands can be considerably more agile in its operation.
There's a human error factor involved, but only because the humans in
question are doing a lot of other jobs in addition to operating ham
equipment and time and attention are on a very short budget.
I do agree that it's worth documenting it all in detail organized by
task/procedure, that's a familiar format for the astronauts to deal
with. A good model for the documentation would be the normal and
emergency operations checklists for any airplane's pilot's operating
