LIRC - Failed to initialize hardware - Mac & IrDroid

Hello again,

So I've made some good progress thanks to Alec & Bengt, but it seems that
my Lirc install just won't work with my IrDroid. I managed to use Bengt's
IrScrutinizer to capture and export the .conf file for my custom remote,
and Lirc doesn't seem to have an issue parsing it. But somehow it just
won't initiate the hardware.

To be specific, I'm running Lirc 0.9.4d installed via MacPorts on macOS
Sierra - https://ports.macports.org/port/lirc/summary

Here's the error log that I get when running Lirc as a daemon
"interactively"...

And for reference, the relevant info from lirc_options.conf:

[lircd]
nodaemon        = False
driver          = irtoy

[lircmd]

# code1 = /usr/bin/setfacl -m g:lirc:rw /dev/uinput
# code2 = ...


# [lircd-uinput]
# release-timeout = 200


I have tried setting the device to cu.usbmodem*** and tty.usbmodem*** with
no luck. (I used both of these successfully with IrScrutinizer, so I know
they're the right devices.)

I tried a full restart to ensure the device wasn't being "held onto" by
some other process, with no luck. I do know that my Mac can see and use it,
as I was able to capture my remote via IrScrutinizer and then transmit the
codes back out of the device and the "flameless candles" turned on and off
appropriately per command. It just seems something is messed up with Lirc.

Any and all help would be sincerely appreciated! :-)

Thx,
