First step is to identify the device associated with our device. This is made by command: |
|||
cat /proc/bus/input/devices | grep -n10 07ca |
|||
This command will display an output like this: |
|||
I: Bus=0003 Vendor=07ca Product=a815 Version=0200 |
|||
N: Name="IR-receiver inside an USB DVB receiver" |
|||
P: Phys=usb-0000:00:13.2-4/ir0 |
|||
S: Sysfs=/class/input/input8 |

U: Uniq= |

H: Handlers=kbd event8 |

B: EV=3 |

B: KEY=3c0110 10200000000000 0 8400 90c0300801 1e060000000000 ffc |
|||
The information that we need is the '''input device number''' that in this case is '''/class/input/input8''' |
|||
This means that the device associated whith IR is |
|||
/dev/input/event8 |
|||
So we must modify the lirc configuration that is in '''/etc/sysconfig/lircd''' or '''/etc/lirc/hardware.conf''' (change from distribution to other) this parameters: |
|||
... |
|||
DRIVER="devinput" |
|||
... |
|||
DEVICE="/dev/input/event8" |
|||
... |
|||
Second step is to generate the codes list by lirc tools. |
|||
ATTENTION! the files provided by lirc in folder /usr/share/lirc-remotes/avermedia/ not work every time so we need to generate a file manually. |
|||
We need to stop lirc first by this command: |
|||
/etc/init.d/lircd stop |
|||
Now we can generate the /etc/lircd.conf with '''irrecord''' by this command: |
|||
irrecord -H dev/input -f -d /dev/input/event'''X''' /etc/lircd.conf |
|||
but first you must replace the '''X''' with the number of the device. In my case i have /dev/input/event8 so i put '''8'''. |
|||
Follow the istructions on screen for build the file. Press RETURN then old down any key of remote control for find GAP value. |
|||
If the device just choise it's right we can see a progressive dot displaying. We gap search is done we must put a name for the key and press ENTER and then the relative button on remote control. This for '''all key in the remote control'''. To end the procedure we con press ENTER. |
|||
Some distribution need the file in /etc/lirc/ so we can copy the file in this way: |
|||
cp /etc/lircd.conf /etc/lirc/ |
|||
Finally we restart lirc with: |
|||
/etc/init.d/lircd start |
|||
We can use the LIRC front-end '''irkick''' for settings the remote control keys or build manually the '''~/.lircrc''' file. |

Revision as of 18:07, 17 January 2010
A DVB-T USB device from AVerMedia.
It is perfectly supported in Linux, even the IR remote.
Very powerful at bad conditions but not stable for 24x7 use.

Firmware
Firstly, you need to copy the following firmware dvb-usb-af9015.fw in your /lib/firmware/ directory, or in the directory where your system will search for it.
Drivers
It is supported in the latest v4l-dvb, so you have to download them first. Either getting [3] or using mercury See the How to Obtain, Build and Install V4L-DVB Device Drivers for all the details.
IR Remote Support
The latest developtment version of the driver gives support to the RM-FP remote control (thanks to Jose Alberto Reguero [4]. But there are other remote control versions bundled with the device. RM-KS is one of those. Taking a look into the files that the CDROM driver installs, there are five files named: AP6RMFP.BIN, AP6RMHR.BIN, AP6RMHV.BIN, AP6RMJH.BIN, AP6RMKS.BIN, where the correct IR table to be used with each remote control (FP, HR, HV, JH, KS) is given.
UPDATE: Support for RM-KS remote is already included in this mercury repository [5]
Download and compile the drivers, and then use the option remote=5 when dvb-usb-af9015 module is loaded. In debian that is made adding (as root) a file called, for example, dvb, in the directory /etc/modprobe.d/ with the line
options dvb_usb_af9015 remote=5
LIRC Configuration
First step is to identify the device associated with our device. This is made by command:
cat /proc/bus/input/devices | grep -n10 07ca
This command will display an output like this:
I: Bus=0003 Vendor=07ca Product=a815 Version=0200 N: Name="IR-receiver inside an USB DVB receiver" P: Phys=usb-0000:00:13.2-4/ir0 S: Sysfs=/class/input/input8 U: Uniq= H: Handlers=kbd event8 B: EV=3 B: KEY=3c0110 10200000000000 0 8400 90c0300801 1e060000000000 ffc
The information that we need is the input device number that in this case is /class/input/input8 This means that the device associated whith IR is
/dev/input/event8
So we must modify the lirc configuration that is in /etc/sysconfig/lircd or /etc/lirc/hardware.conf (change from distribution to other) this parameters:
... DRIVER="devinput" ... DEVICE="/dev/input/event8" ...
Second step is to generate the codes list by lirc tools. ATTENTION! the files provided by lirc in folder /usr/share/lirc-remotes/avermedia/ not work every time so we need to generate a file manually. We need to stop lirc first by this command:
/etc/init.d/lircd stop
Now we can generate the /etc/lircd.conf with irrecord by this command:
irrecord -H dev/input -f -d /dev/input/eventX /etc/lircd.conf
but first you must replace the X with the number of the device. In my case i have /dev/input/event8 so i put 8. Follow the istructions on screen for build the file. Press RETURN then old down any key of remote control for find GAP value. If the device just choise it's right we can see a progressive dot displaying. We gap search is done we must put a name for the key and press ENTER and then the relative button on remote control. This for all key in the remote control. To end the procedure we con press ENTER.
Some distribution need the file in /etc/lirc/ so we can copy the file in this way:
cp /etc/lircd.conf /etc/lirc/
Finally we restart lirc with:
/etc/init.d/lircd start
We can use the LIRC front-end irkick for settings the remote control keys or build manually the ~/.lircrc file.
There is a lot of information on how to make lirc work in Hauppauge_WinTV-NOVA-T-Stick#Remote_Control_Support
Possible issues
Due to some problems with the HID devices, in some machines the IR reception is buggy [6] (i.e. irw gets correctly first button pressed, but then gets stuck in a weird loop where the button seems pressed all the time) To solve this, you can create the file /etc/modprobe.d/usbhid containing:
options usbhid quirks=0x07ca:0xa815:0x04
and then execute
$ sudo update-initramfs -u
and reboot. The problem should be solved that way.
Not stable in 24h/7 use. After a few days recordings have a size of 0 bytes. Only known solution: Unplug the device for 10s and do a reboot.
Test your drivers
Once compiled you can try this: Testing_your_DVB_device. Kaffeine seems the easiest/fastest way to check if it works.
Reception Quality
Compared Avermedia DVB-T Volar X vs. Club 3D ZAP250m (one of the best devices in 2006) at bad conditions at the same PC and the same antenna:
Signal strength at 578000000 Hz: 40333 vs. 15420 Signal strength at 690000000 Hz: 28143 vs. 19275
