Subject: [linux-media] Strange behavior between Terratec Cinergy HD RTL2838 & Alfa AWUS036h RTL2870
Date: Wed, 23 Jan 2013 11:16:45 +0100	[thread overview]
Message-ID: <CAJscJ6mjUgFt4Tvo9Pa+FqhNs0=N31xFL0yJFDg_2J_sWTBwng@mail.gmail.com> (raw)

Hi to u all !
I'm using Xubuntu 12.10, v4l latest media_build, with Alfa Network
AWUS036H (rtl2870) and a Terratec Cinergy HD (rtl2832).
These two cards works flawlessly, but not together : I need to
manually power off the Alfa Network card in order to get TV image with
the Terratec Cinergy HD.
If I use kaffeine or me-tv with AWUS036H power on, display is crappy
and scan with Terratec is almost impossible.
If I power off the AWUS036h usb card, everything with the Cinergy card
works as expected.
