QHY issues was created by hy

I recently encountered a few issues with my QHY5L-ii mono guidecam. I somehow managed to fix them, but am sending this because:
  • Perhaps it'll help others
  • I have no idea why these things might happen, solutions below are hacks, the problems may happen again, what might I do to prevent this?
  • I need to vent ;)
I'm running KStars/Indi/Ekos on the Nov 23rd Raspbian release: Linux raspberrypi 5.4.79-v7l+ #1373 SMP Mon Nov 23 13:27:40 GMT 2020 armv7l GNU/Linux, and running the latest kstars source.

Connection issues:
First off, when I tried to start KStars and connect to Indi, my QHY guide camera was not found. Of course I first suspected bad cables or a bad camera, but, testing those with my backup RPi worked fine. The backup was running older software (but the same Rasbpian release). I noticed that on the 'production RPi' the linux 'lsusb' command did not show the camera, but the 'usb-devices' command did. That gave me the idea that perhaps there was a bad udev rule (given my recent adventures with udev). I checked the differences in /lib/udev/rules.d/* between the two machines, and eventually suspecting gpio, I swapped in the older version of '/lib/udev/rules.d/60-rpi.gpio-common.rules and, sure enough (after a boot), the camera was now visible on 'lsusb' and indi now found the camera.

I wish that I could say all was working then, but...

Camera issues:
Though Indi could now connect and communicate with the camera, it failed to take a picture. I tried the '/usr/bin/qhy_ccd_test' program, and it connected, communicated, but couldn't download a picture either. Given the above paragraph, I again suspected something bad in the installation, and found and swapped in the drivers (in /usr/lib/arm/linux/gnueabihf/libqhyccd.so /usr/lib/arm/linux/gnueabihf/libqhyccd.so.20) from the working older setup to the newer setup. Happily, after doing that, things are working fine now.

Not sure what caused this to happen,

I am having the same problem however my set up is direct from my laptop, no RPi. It isn't the camera as it works in Firecapture so it is obviously the driver in KStars/Ekos. It worked fine on Tuesday not on Wednesday nights. I think that I may have updated the program on the Wednesday as I am having issues with a Meade dsi.
Not being computer savvy I don't know what I can do to fix this myself. I don't have a copy of the previous version of the driver either.
Any suggestions

Same problem here with a 5L-II color
2021-01-24T18:27:50: [ERROR] GetQHYCCDSingleFrame error (-1)
Tried the update, tired the Nightly build and a few re-installs from the ground up, still no luck. Camera works in NINA on Windows and oddly enough will occasionally successfully get a picture after a very long download period if I just use the set exposure butting within the INDI control panel vs EKOS CCD interface. Was working great a week ago. On Ubuntu 20.04.1 if that helps any.

I had the same problem, too. Replacing the QHY library as suggested by Hy fixed it — at least when test running the camera without anything else connected. When using with Ekos, the same problem persist when I use at the same time the INDI driver for the filter wheel QHYCFW2. When I disconnect it the camera takes again images happily.
