I have two cameras connected to my computer, both with a ZWO filterwheel: An ASI2600 with the 36mm 7-filter wheel, and an ASI1600 with the 5-filter EFWmini. They used to show up as wheels ASI EFW 0 (7-slot) and ASI EFW 1 (5-slot). For both I have set up the filter names, and for the 7-slot wheel I also set up filter focus offsets and AF locks.

Obviously this worked flawless so far because I always plugged the compunent in the same way. But recently I managed to switch the two cables of the cameras (the FW are connected to the internal hubs of the cameras) when plugging them into my mount computer. After starting INDI, the 5-wheel was wheel 0, and the 7-wheel was 1. The really bad part however was that all settings were deleted and a default configuration was created, without my focus offsets etc.

Is there an easy way to prevent that from happening again? The standard way to give unique names to devices via udev doesn't work for ZWO units, as they are HID devices :(
Any tips?
