#95 iOptron SmartEQ pro+ tracking issue

[Stoyan Kurtev]

Hi! I have iOptron SmartEQ pro+ with HC8408. However, then plate solved with Stellarmate, it won't track with the speed of the Earth rotation 90% of the time. I am using ZEQ25 driver. I was told to try INDI iEQ driver, but it won't work. These are the iEQ drivers I can see with the results when trying to use them:

Driver iOptron AZ Pro - indi_ioptronv3_telescope - Read command error - Timeout error
Driver v3 - indi_ioptronv3_telescope - Read command error - Timeout error
Driver iEQ Legacy - indi_ieqlegacy_telescope - Only received #10 bytes, expected 7. And keeps giving me timeout and mount motion errors.
Driver ZEQ25 - indi_lx200seq25 - Working and operating the mount, but not tracking correctly
Driver iEQ30 - indi_lx200seq25 - Working and operating the mount, but not tracking correctly
Driver iEQ45 - indi_lx200seq25 - Working and operating the mount, but not tracking correctly
Driver iEQ30 Pro - indi_ieq_telescope - Mount with code 8498 is not recognized.
Driver iEQ45 Pro - indi_ieq_telescope - Mount with code 8498 is not recognized.

Is there another driver I have to install and how? Also, the guiding stucks at RA drifting. I am using SV165 guidescope and SV105 guidecam (optionally QHY guidecam can be used). Eventually, if it goes through and starts guiding, it won't operate and correct the mount at all. Is it because of the driver or some mount motherboard issue? How can I troubleshoot it?

Edit
The HC8408 version is 150302. OK, as per the motherboard driver v1220/v1216 I have the SmartEQ pro, not the Pro+. Then why I have a user manual for Pro+ with the mount?
