Hello,

Since I switched from Astroberry (Raspbian 32 bits) to Ubuntu 21.10 64 bits, in order to solve an issue with my Canon RP eos, INDI can no longer control my Celestron SCT focuser.

Now I just confirmed the focuser is all right using my Windows 10 laptop.

I can see my device in the lusb list but I cannot see any trace of it in the /dev directory or subdirectories.

(I can see for instance my mount at /dev/serial/by-id/usb-FTDI_FT230X_Basic_UART_D3090IHN-if00-port0)

My focuser is connected to the hub of my CEM40.

I also connected it directly to the PI without any success.

As anyone ever run into this problem before?

Hi again,

I just found out, after thorough research, that this is not an INDI problem per se, but rather an Ubuntu problem.

The problem was introduced by the version 21.10.

It has to do with the way serial ports are managed by the OS on a Raspberry Pi.

For more details and for the fix, see askubuntu.com/questions/1371150/usb-seri...update-from-21-04-to
