Magic Trackpad 2 over USB

I have been using my magic trackpad 2 over bluetooth but bluetooth support in linux has been a little buggy lately so I would like to use it over USB instead.

I'm curious if anyone else is using one successfully over USB or if anyone has any ideas on troubleshooting it.

can see it in lsusb.py (other devices filtered for easier reading):

% lsusb.py 
usb1              1d6b:0002 09 1IF  [USB 2.00,   480 Mbps,   0mA] (xhci-hcd 0000:00:14.0) hub
  ...
  1-10              05e3:0608 09 1IF  [USB 2.00,   480 Mbps, 100mA] (Genesys Logic, Inc. Hub) hub
    ...
    1-10.4            0a05:0002 09 1IF  [USB 1.10,    12 Mbps, 100mA] (Unknown Manufacturer) hub
      1-10.4.1          05f3:0081 09 1IF  [USB 1.10,    12 Mbps,  50mA] (PI Engineering Kinesis Keyboard Hub) hub
        ...
        1-10.4.1.4         05ac:0265 00 0IFs [USB 2.00,    12 Mbps,      ] (Apple Inc. Magic Trackpad 2 CC2033202L6J2XQA5) 
..

lsusb sees it as a DAC which seems a bit odd (perhaps because it can do haptic feedback?):

% lsusb | grep 05ac:0265
Bus 001 Device 021: ID 05ac:0265 Apple, Inc. USB Audio DAC

I've tried running evtest on every device in /dev/input/event* and touched the touchpad with no output. It seems as though no event driver is created for it over USB. Please let me know if you have any ideas or insights.
