Wacom tablet stops working when fwupd runs

[Jason Gerecke]

Certain Wacom tablets appear to be incompatible with fwupd and stop working as soon as the fwupd service starts. Because the fwupd service starts a few seconds after the desktop loads on my test machine, the tablet initially appears to work after a reboot but then "disappears" (no longer listed in xsetwacom) after perhaps 30 seconds. In addition to the tablet disappearing, the following message is logged: `failed to add USB device <VID>:<PID>: Failed to get feature report: endpoint stalled or request not supported`

More details in the upstream bug report: https://github.com/hughsie/fwupd/issues/882. A patch has been accepted and should be present in the next release.

This affects bionic, cosmic and disco.
bionic (1_0_X branch) patch: https://github.com/hughsie/fwupd/commit/282c7112a99585d66eaedb039fb0d72e3e0f120d
cosmic and disco (1_1_X branch) patch: https://github.com/hughsie/fwupd/commit/c9cf34ff00e48a6b247c6b6e4bc05f5c7dc3c1fe

[Mario Limonciello (superm1)]

As a mitigation for now anyone affected can workaround by disabling the appropriate wacom plugin in /etc/fwupd/daemon.conf.

disco has 1.2.5 which has a fix for this.

[Mario Limonciello (superm1)]

This was fixed in bionic when 1.2.10 was backported there.
