 Got a first pass at the main GUI loop for Fern hashed out.  GUI programming is
 fucking miserable.

+Observations:
+
+* It's only the keyboard disconnecting.  The mouse is also plugged into the same
+  USB hub, and that doesn't seem to get disconnected (the "mouse" in that log
+  output is the virtual one the UHK uses to do mouse stuff).
+* I'm pretty sure this happens regardless of what USB port it's plugged into.
+  I'm going to try plugging it into a different port on the hub, and if that
+  fails, into the monitor hub, and maybe into the work laptop itself.
+* My Realforce did the same thing, so it can't be specific to the keyboard.
+
+What the fuck, man.
