Hi community,

After many months of good operations, my ioptron CEM120EC mount is giving me problems.
More specifically connectivity problems. I can connect to the mount but it then gives me an error message: 

[ERROR] Read Command Error. Timeout error (see attached driver log).

The mount loses its bearings and stops functioning well. Another message I sometimes get is:

Error setting RA/DEC

I recently updated my OS (sudo apt update && sudo apt upgrade); maybe there is a connection there?

I am running Astroberry on a Pi4.
The mount is connected directly to the Pi through a USB cable.

I have tried different ports on the pi and I tried to connect through a passive USB hub. No improvement.

Any suggestions on what can be wrong and how to fix it?

Best regards,

Marcel Noordman

I can get the mount moving again by disconnect and connecting again.

Also interesting that previously the driver did not pick up the right baud rate from the config (had to set it by hand).
As the connectivity problems started, the baud rate setting problem dissapeared.

Any suggestions on what can be wrong and how to fix it?
