I came across a strange issue with a QHY 5r-IIC camera. The Images don't download until I delete the config.xml.default file for the camera in the .indi folder. I haven't changed any config for it, so no idea what could cause the issue. The log is heavily spammed with the following two lines, when the problem persists:
Can you help us by pinning down what config would cause this? Maybe setting the USB speed or traffic causes this? Ok, so instead of deleting the whole config file, I want you to delete each XML property from it and then reload the driver and see what happens. When you delete the problematic property, the driver would start working again and we'd know what led to this.
