[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:

I strongly suggest you upgrade to a supported version of Fedora. It will have a newer kernel which could possibly solve your problem. F24 is EOL.

Thanks Samuel, as it turns out this morning I upgraded to f26.
dvb_usb_rtl28xxu has issues with this card, it fails to tune. However, once (the system was rebooted a number of times) running scandvb managed to tune one multiplex (out of five here), the same one on all four tuners (I have two cards installed and each has two USB tuners).
I am ready to provide logs and run tests if it helps.
I am now running with some old USB tuners I had around, with some failures which I will post separately.
cheers

What do you mean by a card with USB tuners? Do you have USB expansion cards in your computer and you are plugging the tuners into those?
I would suggest that you try to use one tuner at a time first. That makes it easier to isolate problems and there is less chance of various applications getting confused about which tuner it is talking to.

No. The card (PCI Leadtek Winfast DTV2000 DS PLUS TV) is a PCI device but it actually has two USB devices on board. The card is not showing in 'lspci' because it only uses power from PCI. It shows as two USB devices in 'lsusb'.
I have two of these cards installed, hence four tuners. Removing a card is a bit more involved than just plugging a USB stick.

Thanks

This seems to be due to usb_control_msg() having changed in recent kernels requiring dma capable transfer buffer.
ATM beyond me to fix.
