Hi JC,

Thank you so much for sharing this, I have tried that on my Astroberry, now gain and offset will be adjustable. Meanwhile, the known problem of jamming will still appear after we make the change.

The jamming problem won't be resolved by reseting the USB port. I have tried the following when EKOS and KSTARS are on and off:

astroberry@astroberry:~ $ dmesg | grep -i qhy
[ 10.032707] usb 1-1.1.2: Product: QHY-8 S
[ 10.032721] usb 1-1.1.2: Manufacturer: QHY-CCD
astroberry@astroberry:~ $ sudo sh -c "echo 0 > /sys/bus/usb/devices/1-1.1.2/authorized"
[sudo] password for astroberry:
astroberry@astroberry:~ $ sudo sh -c "echo 1 > /sys/bus/usb/devices/1-1.1.2/authorized"
sh: 1: echo: echo: I/O error

However, since the camera technically is working now, thank you again for sharing your work.
