Hi Antti
With the Cinergy stick alone, dvb_usb_af9015 is predictably loaded, but
doesn't prevent dvb_usb_it913x from working nicely.
If an afatech 9015 stick is connected, such as an AverTV Volar Black HD
(A850), it will be recognized and doesn't affect the other device.
*But* it runs into trouble if the two devices were connected at bootup,
or if the Cinergy stick is inserted after the other one :
I am not sure what you do here but let it be clear.
There is same ID used by af9015 and it913x. Both drivers are loaded when
that ID appears. What I understand *both* drivers, af9015 and it913x
should detect if device is correct or not. If device is af9015 then
it913x should reject it with -ENODEV most likely without a I/O. If
device is it913x then af9015 should reject the device similarly. And you
must find out how to do that. It is not acceptable both drivers starts
doing I/O for same device same time.
regards
Antti
