G'day Brent,
If a device is 'unplugged' (see later) then it is probably that your
driver (kext) will be unloaded. This will automatically happen after
at least 1 minute with no instances extant in the kext. I'd say that
something like this happened, perhaps the system slept the bus or
something.
To answer question one is a bit more difficult. If you unplug and plug
your device again does the driver turn up again (tty.???). If not it
looks like something is happening to your kext or perhaps to the kernel
state itself.

Questions:
1. I thought kexts were kept in wired memory and remained loaded even
if you deleted the executable. Am I wrong about this? I think my
experience with previous versions of Mac OS gave me this impression.
Why would kextd be running on my driver if it had been loaded for
three days?
2. Where did my kext go? I certainly didn't touch it. Do the messages
from the journal have any significance?
Many thanks if you can shed any light on what's just happened here.
Cheers,
Brent Marykuca
