Hi Jürgen,

Any chance we could see the output of `dmesg` and `lsusb` from your astroberry? I'd be interested in knowing if you have the same serial controller I do.

I have a suspicion that there might have been a hardware change. Knowing what you have would answer that question.

Hi Hades,

Unfortunately, I don't have a windows machine to test with. I'll try on my Mac later tonight.

I was pretty excited to have the USB port, and to get away from the EQMod cables. Thankfully they are still an option if I can't get the USB port working.

Hi Androgena,
here you see the lsusb from my EQ6-R:


As already worte by Seescho it is important to set the Baud rate to 115200, otherwise ist doesn't work.

Once the mount is seen by EKOS I have the following informations in the INDI mount tab "firmware": Firmware 0307, mount code 0x23.

Do you have tryed another USB cable? Hope you get your mount working!

Best regards


Jürgen

I just saw, that you already posted your lsusb... I try to get the detailed lsusb output after work, just copied the one line output after my photo session last night.

My EQ6-R has at least a different product ID.

Hi Wouter,

I tried the scan ports button. Also went through the device mapping process on the port 8624 page. No luck with either.

It looks like my mount has a different serial controller than other known working mounts. Jürgen reports he has the Prolific 2303, where mine has the 23d3. His is a pretty standard TTY device. Mine shows up as a human input device,

I should reach out to SkyWatcher to see what they have to say.

Thank you, Jürgen. I suspected that might be the case.

The EQMod cable still works in the hand controller port. I'll be okay if we can't figure this out. :)

Hi Edgar,

The mount doesn't even show up as a com port. Unfortunately, it's not the bitrate setting.

One other possible lead... It looks like the version of the Kernel I'm running may not have a driver for this serial controller.

I found this document suggesting that 23d3 support was added in Linux 5.5

cateee.net/lkddb/web-lkddb/USB_SERIAL_PL2303.html

It looks like 4.4 is the latest Kernel available for Raspbian.

en.wikipedia.org/wiki/Raspberry_Pi_OS

I might try compiling a newer kernel. I'm not sure how much of a pain that's going to end up being, though.

Yes, I was sort-of suspecting it's a HID. Seems to get more and more common, and I don't like it too much. It's asking for trouble when it comes to firmware upgrades. The ZWO EAF is also such a 'problem child'. FW update software only for windows, but contrary to standard COM/USB ports where you usually can run that software in wine, the HID support in wine is not up to that :( Not even vmware worked.

So I'm afraid you will need a dedicated driver to use that USB port.

Then again - isn't eqmod supposed to use the HC port anyhow, and USB only if used through the HC? What would be the advantage using that USB port?

How about backing up the SD card and installing Ubuntu 20.04 with KStars on it? May be easier than compiling your own kernel.

I can confirm the mount works with the latest Kernel releases.

Current versions of Stellarmate and Raspberry Pi OS require an unsupported kernel upgrade to make the mount work. I'm sure we can expect official support eventually, but this is a Raspbian thing, and not a Stellarmate thing.

This process worked for me: www.raspberrypi.org/documentation/raspbi...ations/rpi-update.md

Here's my release information:
stellarmate@stellarmate:~ $ uname -a
Linux stellarmate 5.10.0-v7l+ #1382 SMP Tue Dec 15 18:23:34 GMT 2020 armv7l GNU/Linux

No LSB modules are available.

The port needs to be set to 115200 as per the other comments.
