I am still getting this error on the latest 1.4.4 Rpi3 and Rpi4 versions. I ran software updater today, Sept. 29, on both machines and the rules file in lib\udev\rules.d was updated with the 9/28/2019 85-QHYCCD.rules. I have rebooted both machines a number of times.
My camera is the Orion SSAG. It has worked well in the past connected as a QHY. On Stellarmate, the camera is listed as QHY-M-. In the rules file, under SSAG, it says stuff like idproduct "0011" and QHY5Loader.hex.
It connects with no problems, but will not take a picture. In the camera module it says capture aborted and in another place it says GetQHYCCDSingleFrame error (-1)
Do I need to run a firmware update or downgrade on the camera somehow?
I have just rebuilt my OdroidXU4 and this new version of the QHY driver works wonderfully well.
Thank you for sorting this issue.

Looks like I am in the same boat as you. Both my PoleMaster and QHY5LII-C are throwing the [ERROR] GetQHYCCDSingleFrame error (-1) whenever EKOS requests a image to be taken. I can see the image being downloaded in QHY logs but the driver cancels the load.
Thank you for the good report. Here were my steps yesterday. I used Synaptic to see what QHY drivers and applications were installed. Then I removed any and all. After completion, I reinstalled indi-QHY. I will validate today what the state of both devices are in. Would you share any additional steps you took?
On a whim, I decided to check SYSLOG for any errors while testing my QHY devices with Polar Alignment and EKOS. I found the smoking gun. My error is in indi_qhy_ccd. The OS says using a USB before claiming it is the reason for the halt. I thought it strange for the QHY logs to yield an error when nothing previous to error indicated the need for an alert. Yes. The OS can stop KSTARS from operating.
