My RasPi(Raspbian 9.4 (stretch)+livimdi 1.7.4) cannot communicate with ZWOASI EFWmini as follows. I have installed dependencies, sudo apt --fix-broken install, and cp udev rule based on ASI website. (Last year, it did worked with jessie+libindi_1.4.1)
My final goal is to do this on PizeroW, but did not work. Then I retried it on Pi3B, but not worked. Thank you for your kind advice.

Can I have the meaning of this message, and useful URL or something to solve the issue?
>Driver indi_asi_wheel: FW ID: 0 FW Name: EFW enumerate? false
Any small advice should be appreciated.

Likely nothing that really helps you, but I do get that message, too, from my EFWmini. But it's working without issues, so at least it's not a showstopper...

Thank you DerPit.
So you do't get message like;
>No EFW.CONNECTION.CONNECT from localhost:7624

I have installed libindi, and not any third party driver, just rules such as;
>$sudo cp efw.rules /lib/udev/rules.d
>Replug filter wheel
One option is to get the old version, meaning jessie+libindi_1.4.1, because I did not have any issue last year.

I have also consulted ASI, and got shown below;
On my script is
indi_setprop "EFW.CONNECTION.CONNECT=On"
Correct property of connection is
indi_setprop "ASI EFW.CONNECTION.CONNECT=On"

All property need "ASI "
I am not sure why my wrong script did worked last year on my same board with jessie+libindi_1.4.1.
Anyway, it does work, and now I will try it on my RPi0W.

Thanks all.
