keyboard and docking pad

[wigan]

Debian Mobian
vmlinuz-6.1-sunxi64

Docking bar doesn't work w/ the fon in the keyboard (connected to the pinefon
USB-C port).  The keyboard manual says (in four languages)...

  When coupled w/ the keyboard the pinefone's USB-C is to be used 'solely' for
  data and peripherials.

I take the docking bar to be a peripherial.  I've read through the relevant
material w/o finding a way through.
