Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

|
||
2004-05-14 - firmware loader is working
|
||
2004-05-11 - start writing the driver
|
||
|
||
1. How to use?
|
||
NOTE: This driver was developed using Linux 2.6.6.,
|
||
it is working with 2.6.7 and above.
|
||
|
||
Linux 2.4.x support is not planned, but patches are very welcome.
|
||
|
||
NOTE: I'm using Debian testing, so the following explaination (especially
|
||
the hotplug-path) needn't match your system, but probably it will :).
|
||
|
||
The driver is included in the kernel since Linux 2.6.10.
|
||
|
||
1.1. Firmware
|
||
|
||
The USB driver needs to download a firmware to start working.
|
||
|
||
You can either use "get_dvb_firmware dibusb" to download the firmware or you
|
||
can get it directly via
|
||
|
||
for USB1.1 (AN2135)
|
||
http://www.linuxtv.org/downloads/firmware/dvb-dibusb-5.0.0.11.fw
|
||
|
||
for USB1.1 (AN2235) (a few Artec T1 devices)
|
||
http://www.linuxtv.org/downloads/firmware/dvb-dibusb-an2235-1.fw
|
||
|
||
for USB2.0 (FX2) Hauppauge, DiBcom
|
||
http://www.linuxtv.org/downloads/firmware/dvb-dibusb-6.0.0.5.fw
|
||
|
||
for USB2.0 ADSTech/Kworld USB2.0
|
||
http://www.linuxtv.org/downloads/firmware/dvb-dibusb-adstech-usb2-1.fw
|
||
|
||
for USB2.0 HanfTek
|
||
http://www.linuxtv.org/downloads/firmware/dvb-dibusb-an2235-1.fw
|
||
|
||
|
||
1.2. Compiling
|
||
|
||
Since the driver is in the linux kernel, activating the driver in
|
||
your favorite config-environment should sufficient. I recommend
|
||
to compile the driver as module. Hotplug does the rest.
|
||
|
||
1.3. Loading the drivers
|
||
|
||
Hotplug is able to load the driver, when it is needed (because you plugged
|
||
in the device).
|
||
|
||
If you want to enable debug output, you have to load the driver manually and
|
||
from withing the dvb-kernel cvs repository.
|
||
|
||
first have a look, which debug level are available:
|
||
|
||
modinfo dib3000mb
|
||
modinfo dib3000-common
|
||
modinfo dib3000mc
|
||
modinfo dvb-dibusb
|
||
|
||
modprobe dib3000-common debug=<level>
|
||
modprobe dib3000mb debug=<level>
|
||
modprobe dib3000mc debug=<level>
|
||
modprobe dvb-dibusb debug=<level>
|
||
|
||
should do the trick.
|
||
|
||
When the driver is loaded successfully, the firmware file was in
|
||
the right place and the device is connected, the "Power"-LED should be
|
||
turned on.
|
||
|
||
At this point you should be able to start a dvb-capable application. For myself
|
||
I used mplayer, dvbscan, tzap and kaxtv, they are working. Using the device
|
||
in vdr is working now also.
|
||
|
||
2. Known problems and bugs
|
||
|
||
- Don't remove the USB device while running an DVB application, your system will die.
|
||
|
||
2.1. Adding support for devices
|
||
|
||
It is not possible to determine the range of devices based on the DiBcom
|
||
reference designs. This is because the reference design of DiBcom can be sold
|
||
to thirds, without telling DiBcom (so done with the Twinhan VP7041 and
|
||
the HAMA device).
|
||
|
||
When you think you have a device like this and the driver does not recognizes it,
|
||
please send the ****load*.inf and the ****cap*.inf of the Windows driver to me.
|
||
|
||
Sometimes the Vendor or Product ID is identical to the ones of Twinhan, even
|
||
though it is not a Twinhan device (e.g. HAMA), then please send me the name
|
||
of the device. I will add it to this list in order to make this clear to
|
||
others.
|
||
|
||
If you are familar with C you can also add the VID and PID of the device to
|
||
the dvb-dibusb-core.c-file and create a patch and send it over to me or to
|
||
the linux-dvb mailing list, _after_ you have tried compiling and modprobing
|
||
it.
|
||
|
||
2.2. USB1.1 Bandwidth limitation
|
||
|
||
Most of the currently supported devices are USB1.1 and thus they have a
|
||
maximum bandwidth of about 5-6 MBit/s when connected to a USB2.0 hub.
|
||
This is not enough for receiving the complete transport stream of a
|
||
DVB-T channel (which can be about 16 MBit/s). Normally this is not a
|
||
problem, if you only want to watch TV (this does not apply for HDTV),
|
||
but watching a channel while recording another channel on the same
|
||
frequency simply does not work very well. This applies to all USB1.1
|
||
DVB-T devices, not just dibusb)
|
||
|
||
Update: For the USB1.1 and VDR some work has been done (patches and comments
|
||
are still very welcome). Maybe the problem is solved in the meantime because I
|
||
now use the dmx_sw_filter function instead of dmx_sw_filter_packet. I hope the
|
||
linux-dvb software filter is able to get the best of the garbled TS.
|
||
|
||
The bug, where the TS is distorted by a heavy usage of the device is gone
|
||
definitely. All dibusb-devices I was using (Twinhan, Kworld, DiBcom) are
|
||
working like charm now with VDR. Sometimes I even was able to record a channel
|
||
and watch another one.
|
||
|
||
2.3. Comments
|
||
|
||
Patches, comments and suggestions are very very welcome.
