Subject: libopenobex2: having this package installed delays xorg usb keboard/mouse hotplug by 2 minutes

Date: Sun, 27 Aug 2017 17:45:20 +0200

Package: libopenobex2
Version: 1.7.2-1
Severity: normal

Dear Maintainer,

as the subject says, having this package installed delays Xorg hotplugging
by 2 minutes (and probably others as well). That means when I unplug
my usb keyboard and/or mouse, I need to wait for ~120 seconds (the udev
timeout) to be able to use these devices again. Uninstalling this package
reduces the delay to practically instant.

The reason seems that obex-check-device seems to do something with the
keyboard/mouse, and effectively hangs until udev kills it. udev gives this
in syslog:
