H420 doesn't work on Big Sur
I've tried three different driver versions for my H420 on the 2020 Macbook Pro (M1, Big Sur):
12.0.5 (the one on Huion's website)
12.0.4 (the one in the Google Drive)
Of these, only 12.0.4 the Tablet Driver Panel installed. It detects the tablet (Device Connected), and the green light on my H420 turns on when I touch the pen to the tablet, but the Mac doesn't detect any movement by the pen.
For 12.0.5, no Tablet Driver Panel is installed, but the pen can at least be used to hover around the screen. However, pressing the pen down on the tablet does nothing.
Is there an upcoming update for the H420 on Big Sur? I'm sure the device works fine since it works on Windows, just not on the new Macbook.
