Hi everyone,

So I've got a Meade ETX 90 Maksutov-Cassegrain for planetary imaging, asteroids hunting, camping trips, fun with kids and etc. This one comes with Audiostar hand controller (the speaking one).

Unfortunately, I wasn't able to connect this mount to INDI - tried drivers labeled as "ETX90", "LX200 Autostar" and other "LX*", no luck.
I feel like they've updated a firmware for "Audiostar" line. Please see photo of boot screen in attachment.

Can you advice if it is supported or not?

I will be happy to participate in driver development if it is not supported!

Forgot to mention - I used USB-Serial cable from my iOptron mount. I don't think it should be a problem as it is standard cable and there is the same 4pin socket on Meade hand controller.

It could be the USB chip for Meade.. what's the dmesg output when you plug in the USB?

when I connect my mount USB-serial cable the dmesg output gets appended with:
[  616.155293] usb 1-1.2: new full-speed USB device number 6 using dwc_otg
[  616.288255] usb 1-1.2: New USB device found, idVendor=067b, idProduct=2303, bcdDevice= 3.00
[  616.288268] usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[  616.288278] usb 1-1.2: Product: USB-Serial Controller
[  616.288288] usb 1-1.2: Manufacturer: Prolific Technology Inc.
[  616.291691] pl2303 1-1.2:1.0: pl2303 converter detected
[  616.297204] usb 1-1.2: pl2303 converter now attached to ttyUSB0

Also might worth to mention that log messages per device are empty unless I try "LX 200 Basic" driver , it says: "2020-03-25T15:35:48: [ERROR] Error communication with telescope. "

For all other "ETX*" or "LX*" labeled drivers the log on device tab in INDI Control Panel is empty but main Ekos Setup log window just says "LX200 Autostar is disconnected." (i.e. here I tried LX200 Autostar).

I tend to think that it doesn't like RS232-4pin cable from iOptron.

Just to follow up and for future reference in case anyone bumps into this issue.

I was able to solve it just by using native Meade #505 Cable connection set. Please NOTE - for HC->computer connection you will need to use 6ft 4pin-6pin cable included (3ft one is for HC->HC cloning).
Also, please find photo of this thing in attachment.

Cheers!
