Comment 30 for bug 1589585

What @grofaty was seeing was that his gnome-software was refreshing constantly. He didn't say any warnings were emitted other than when he ran fwupd in verbose mode.

If a user disconnected/reconnected a device gnome-software will refresh, yes. But as mentioned in https://github.com/hughsie/fwupd/issues/48 that's the behavior of gnome-software 3.20.x. Moving to g-s 3.21 and fwupd >= 0.7.1 will prevent that, but won't fix the underlying problem that @grofaty is encountering with a USB device that's dropping on and off the bus.
