Thanks for the info. I’ve read through it and about a thousand other sources over the past week. I’ve learned a lot, but the domain of info is so large that I’m now rather disheartened.
In short, I just need for piaware to see my 978 device. I’ve found the device via journalctl including its serial number. However, neither rtl_test nor rtl_eeprom can see the device, neither by id nor by serial number - they only see the 1080 device. I’ve tried all of this after stopping the piaware and two dump services.
The 978 device is working when I use the stratux rpi image. I’ve dug into stratux a fair amount and, long story short, I have a ton of dishes and laundry that have built up during this effort, so I have to scale back for a while.
My guess is that something is grabbing hold of the device, preventing it from being accessible to the rtl tools. Any ideas on how to know what may have a hold on it, or more importantly, how to force them to let go?
