About two weeks ago I noticed my ASI EAF no longer was being loaded in Ekos in the latest (at that time) nightly version.  I have stable versions that I revert to when these things crop up so this is more just to alert those developing the software.  Since then I have kept up with the updates of Kstars and the various indi libraries and drivers that are made available. So far my focuser still doesn't show up in Ekos.  

 
running apt list --installed|grep asi  returns this:

brian@nanopct4:~$ apt list --installed|grep asi

Jo, (El Corazan)  mentioned in another thread his filter wheel had disappeard recently after an update and noticed the nightly version 99-asi.rules in the rules.d folder was missing the first line. After editing it back, his filter wheel was loading again.  I was also missing that first line, edited it back but it seems to not have changed anything in my case.  

The 99-asi.rules file from the stable version of Kstars (March 1 2021) appears as below:

ACTION=="add", ATTR{idVendor}=="03c3", RUN+="/bin/sh -c '/bin/echo 256 >/sys/module/usbcore/parameters/usbfs_memory_mb'"

# All ASI Cameras and filter wheels

SUBSYSTEMS=="usb", ATTR{idVendor}=="03c3", MODE="0666" 

The 99-asi.rules file from the nightly version is missing that first line.  I'm not sure this is significant but thought I would mention it.

The log file is attached , it looks pretty normal to me but I'm no developer, maybe someone can spot something.

It's not missing, it was removed on purpose and move to INDI Library. So if you install INDI Library latest from GIT, it should install a udev rule file that's generic for all USB devices.

Hi Brian,

The missing line was moved to indilib and changed slightly so that it only changes the memory allocation if it is not already set to something higher. This was on purpose, and seems to be working now, so I do not think this is the issue, unless you did not also update indilib? Something to check anyway.

You can also verify the setting by runningAfter a reboot it may say 16, but after running indi, it should say 256.

Either way, the usb memory allocation shouldn't affect device discovery.

More suspect is the update made on the 19th, to libasi, where the ZWO SDK was updated. Before that, only the version number changed for the release of 1.8.9, nothing else in libasi changed, all the way back to Jan 4. Can you install a version just before March 19 to verify the focuser still works at that point?

I agree, specifying the image buffer memory size is unlikely to affect the recognition of ZWO peripherals when added to the asi.rules file, now that it is already being set globally.

As I wrote earlier, I cannot say for certain that increasing the memory was what fixed the problem in my case, as I also found the efw.rules file that was missing in the udev/rules.d folder. Adding that back together with the modified asi.rules file fixed the problem in my case where the EFW was not recognized. I do not have a ZWO-EAF, so I cannot test that. I am using Moonlite, and that has no problem.

I did not find an EAF.rules file anywhere, so whatever governs the recognition of the EAF is likely contained somewhere else, possibly in the libasi that Jim also suspects. So purging libasi and installing the March 10 version of that library may fix Brian's problem.

Jasem made the first suggestion so I did that first and it fixed it.
I went here  indilib.org/forum/general/210-howto-buil...st-libindi-ekos.html   and followed the directions for "Building Indie from Source".  Thanks everyone for taking the time to help.

That's great! When I last updated Indi from the source about a week ago, that fix was not yet there.
Glad it works now!
I'll rebuild my own drivers then next time and see if that fixes the filter wheel issue as well.
Thanks, Jasem!

PS:  Did this involve a revision of libasi and would just rebuilding libasi have been sufficient?
