138 2004-05-14 - firmware loader is working

140
1411. How to use?
142NOTE: This driver was developed using Linux 2.6.6.,
143it is working with 2.6.7 and above.
144
145Linux 2.4.x support is not planned, but patches are very welcome.
146
147NOTE: I'm using Debian testing, so the following explaination (especially
148the hotplug-path) needn't match your system, but probably it will :).
149
150The driver is included in the kernel since Linux 2.6.10.
151
1521.1. Firmware
153
154The USB driver needs to download a firmware to start working.
155
156You can either use "get_dvb_firmware dibusb" to download the firmware or you
157can get it directly via
158
159for USB1.1 (AN2135)
160http://www.linuxtv.org/downloads/firmware/dvb-dibusb-5.0.0.11.fw
161
162for USB1.1 (AN2235) (a few Artec T1 devices)
163http://www.linuxtv.org/downloads/firmware/dvb-dibusb-an2235-1.fw
164
165for USB2.0 (FX2) Hauppauge, DiBcom
166http://www.linuxtv.org/downloads/firmware/dvb-dibusb-6.0.0.5.fw
167
168for USB2.0 ADSTech/Kworld USB2.0
169http://www.linuxtv.org/downloads/firmware/dvb-dibusb-adstech-usb2-1.fw
170
171for USB2.0 HanfTek
172http://www.linuxtv.org/downloads/firmware/dvb-dibusb-an2235-1.fw
173
174
1751.2. Compiling
176
177Since the driver is in the linux kernel, activating the driver in
178your favorite config-environment should sufficient. I recommend
179to compile the driver as module. Hotplug does the rest.
180
1811.3. Loading the drivers
182
183Hotplug is able to load the driver, when it is needed (because you plugged
184in the device).
185
186If you want to enable debug output, you have to load the driver manually and
187from withing the dvb-kernel cvs repository.
188
189first have a look, which debug level are available:
190
191modinfo dib3000mb
192modinfo dib3000-common
193modinfo dib3000mc
194modinfo dvb-dibusb
195
196modprobe dib3000-common debug=<level>
197modprobe dib3000mb debug=<level>
198modprobe dib3000mc debug=<level>
199modprobe dvb-dibusb debug=<level>
200
201should do the trick.
202
203When the driver is loaded successfully, the firmware file was in
204the right place and the device is connected, the "Power"-LED should be
205turned on.
206
207At this point you should be able to start a dvb-capable application. For myself
208I used mplayer, dvbscan, tzap and kaxtv, they are working. Using the device
209in vdr is working now also.
210
2112. Known problems and bugs
212
213- Don't remove the USB device while running an DVB application, your system will die.
214
2152.1. Adding support for devices
216
217It is not possible to determine the range of devices based on the DiBcom
218reference designs. This is because the reference design of DiBcom can be sold
219to thirds, without telling DiBcom (so done with the Twinhan VP7041 and
220the HAMA device).
221
222When you think you have a device like this and the driver does not recognizes it,
223please send the ****load*.inf and the ****cap*.inf of the Windows driver to me.
224
225Sometimes the Vendor or Product ID is identical to the ones of Twinhan, even
226though it is not a Twinhan device (e.g. HAMA), then please send me the name
227of the device. I will add it to this list in order to make this clear to
228others.
229
230If you are familar with C you can also add the VID and PID of the device to
231the dvb-dibusb-core.c-file and create a patch and send it over to me or to
232the linux-dvb mailing list, _after_ you have tried compiling and modprobing
233it.
234
2352.2. USB1.1 Bandwidth limitation
236
237Most of the currently supported devices are USB1.1 and thus they have a
238maximum bandwidth of about 5-6 MBit/s when connected to a USB2.0 hub.
239This is not enough for receiving the complete transport stream of a
240DVB-T channel (which can be about 16 MBit/s). Normally this is not a
241problem, if you only want to watch TV (this does not apply for HDTV),
242but watching a channel while recording another channel on the same
243frequency simply does not work very well. This applies to all USB1.1
244DVB-T devices, not just dibusb)
245
246Update: For the USB1.1 and VDR some work has been done (patches and comments
247are still very welcome). Maybe the problem is solved in the meantime because I
248now use the dmx_sw_filter function instead of dmx_sw_filter_packet. I hope the
249linux-dvb software filter is able to get the best of the garbled TS.
250
251The bug, where the TS is distorted by a heavy usage of the device is gone
252definitely. All dibusb-devices I was using (Twinhan, Kworld, DiBcom) are
253working like charm now with VDR. Sometimes I even was able to record a channel
254and watch another one.
255
2562.3. Comments
257
258Patches, comments and suggestions are very very welcome.
