Veikk A15 "missing tablet capabilities: resolution"

The Veikk A15 drawing tablet I have used to work, but it's been more than a year since I used it. Now, neither the buttons nor pen cause any effect outside the proprietary driver GUI. `libinput list-devices` shows 2 items for it when plugged in, but also complains, "event17 - VEIKK.INC A15 Stylus: libinput bug: missing tablet capabilities: resolution. Ignoring this device."
Adding a file in /etc/udev/hwdb.d/ similar to this solution and replugging the device didn't resolve the error (also referenced: /lib/udev/hwdb.d/60-evdev.hwdb comments).
The proprietary driver package *was* updated on my system since I used the tablet last, but I can't try going back to an older version as I didn't save the package and the manufacturer has removed the file from their website.
Did I put the wrong info in the file? Alternately, what else should I try?

/etc/udev/hwdb.d/61-veikk.hwdb:

# Veikk A15. Resolution based on driver reported values and a manual measurement
#   of input surface
evdev:input:b0003v2febp0004*
   EVDEV_ABS_00=::200
   EVDEV_ABS_01=::209
