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.

Any idea to fix this behavior please ?
Thanks to u all !
Sounds like USB host controller issue. What is USB controller (AMD SBxxx?)?
Easiest way to work around problem is to put these devices to USB port
that are under different USB HCI.
