[this is a repost of an item I have on the linux-media list]
I have just upgraded to f24. I am now using the standard dvb_usb_rtl28xxu fe
which logs messages suggesting all is well (I get the /dev/dvb/adapter? etc.)
but I get no channels tuned when I run mythfrontend or scandvb.
Is anyone using this combination?
Is this the correct way to use this frontend?
I also built the media tree from source but ended up with the same failure.
BTW:
Until f22 I was using the out of kernel driver from
https://github.com/jaredquinn/DVB-Realtek-RTL2832U.git
but I now get a compile error. I fixed the compile but at load time I see
an error:
