NAK
It's annoying that we have to reset the connectors so much, but
unfortunately there is a reason in this case. The problem is that
chamelium_init() does not get called once per test. At first glance
when running through ./scripts/run_tests.sh this might appear to be the
case, however if you run the test by manually calling the built
chamelium binary (generally useful for debugging the tests themselves
with gdb) it won't actually get called in-between tests.
This being said, I'm all for getting rid of a couple extraneous hotplug
resets if possible, but I'd prefer to avoid breaking the ability to run
the chamelium test binary manually.
