After the latest update(s) the RTL SDR dongles stopped working because the dvb_usb_rtl28xxu doesn't let go of the device anymore. Are there any changes that would make that happen? I'm up-to-date with everything on hardware:/sdr/openSUSE_Tumbleweed as far as I can tell.

Hi Working fine here with dump1090, dvb_usb_rtl28xxu should be blacklisted?
cat /etc/modprobe.d/50-dvb_usb_rtl28xxu.conf blacklist dvb_usb_rtl28xxu
