I could maybe use some advice regarding the "framework" around child devices - as I went with what seemed the most reasonable, but I do get a small issue currently. After the update is done on a child device (that is a device connected to one of our dongles), I get a message from fwupdtool "device version not updated on success, V1 != V2".
The version is updated, but I imagine fwupdtool queries for the new version before the device reconnects itself.

@gdpcastro I think the device version not updated on success is because the parent and the child have the same device-id -- I think you meant to set the logical ID to ota_device.

I've pushed a fixup and probably broken a few things, but be helpful in showing you the way to do this. I hope it's helpful!

I'm going to be on vacation for some days, so this will be on hold for around a week

@gdpcastro I think the device version not updated on success is because the parent and the child have the same device-id -- I think you meant to set the logical ID to ota_device.

I still get device version not updated on success, 1.7.4 != 1.8.13 - might be a problem with the fact that the ota device takes a second to re-pair to the dongle. Not entirely sure how to address it properly. I did try adding some waiting times, but to no avail

I think we're missing a fu_device_add_flag(child, FWUPD_DEVICE_FLAG_WAIT_FOR_REPLUG); somewhere -- i.e. just before the child device "goes away" and "comes back" from the daemon. If the child device never really goes away, then fu_device_sleep() in ->reload() might be your friend.

@gdpcastro I've made a few cosmetic changes, and squashed everything down. Can you test one more time and then please merge. Thanks!

Tests went through :) Merging!
