Hi, I got new GEM45 last week with firmware(210105). I wonder which iOptron I should select. If I select ioptronv3 driver, GEM45 is able to slew. If I select GEM45 indi driver, it get error
"[ERROR] Serial read error: Timeout error. "[2021-02-12T16:14:49.802 CST WARN ][ kf5.ki18n] - "Interpolation {$[~stripAccel %1]} in {$[~stripAccel %1]} failed: Unregistered call to '~stripAccel'."

Someone from iOptron tell me that indi maybe work well with new firmware(210105). These Indi driver may need to update for new firmware. Is GEM45 drive don't support new firmware instead of ioptronv3 driver?

The full name should be v20210105 in www.ioptron.com/Articles.asp?ID=318, but the download link is invalid. My GEM45 just comes with firmware(v20210105).
Hi, Rishigarrod, please let me know the difference if you upgrade to new firmware.

iOptron releases new GEM45 now. Previous GEM45 separates iPolar & USB control into two cable, no usb hub. New GEM45 only has one USB line, which contain iPloar, mount control(FDTI USB serial), USB2.0 hub. I guess it will be something different, especially in power manager. More, new firmware(210105) may also make different communication. We are using Ubuntu 20.04 (aarch64) in SoC Khadas VIM3.

I got my GEM45(firmware 210105) last week, also the actually same USB error in my rpi4b as you. But GEM45 could work well with my another SoC(Khadas VIM3). It seems to rpi4B hardware compatibility( especially power issue), not due to indi driver.
Although GEM45 is able to connect to INDI with GEM45 driver and slew mount, it shows the following error and crashes unexpectedly:
