No stylus found for Wacom HID 49A3 Pen (Latitude 7320)

[Krister Swenson]

I have a Dell Latitude 7320 Detachable with a 7320 Detachable Active Pen (PN7320A). The pen mostly works, aside from a periodic bug (https://github.com/linuxwacom/input-wacom/issues/281). It shows up as a Wacom pen from libinput:

I cannot configure it via the Wacom Tablet settings in the control center. It always says "No stylus found" despite being able to use the stylus with applications such as Xournal++.

Thank you for your bug report. Could you add the output of
$ libwacom-list-local-devices
?

libwacom-list-local-devices prints nothing.

[Sebastien Bacher (seb128)]

it sounds like libwacom isn't knowing about it then, reassigning. You might want to report the issue directly to upstream on https://github.com/linuxwacom/libwacom/issues

The upstream bug report is here: https://github.com/linuxwacom/libwacom/issues/432
