[linux-dvb] iVOGUE DVB20 USB box?

[Georg Sassen]

Hi,

yesterday I got this thing and now I'm trying to make it work somehow.

http://www.pcstore.de/storeshop/artikeldet.php?proid=5518

It has a red and a green LED inside and an infrared remote control  
receiver, I haven't opened it yet.

after loading the Hanftek firmware:

Bus 005 Device 004: ID 15f4:0015 HanfTek

Jul 10 19:29:59 piccolo kernel: dvb_usb_umt_010 5-1:1.0:  
usb_probe_interface - got id
Jul 10 19:29:59 piccolo kernel: dvb-usb: found a 'Hanftek UMT-010 DVB- 
T USB2.0' in warm state.
Jul 10 19:29:59 piccolo kernel: dvb-usb: will pass the complete MPEG2  
transport stream to the demuxer.
Jul 10 19:29:59 piccolo kernel: DVB: registering new adapter (Hanftek  
UMT-010 DVB-T USB2.0).
Jul 10 19:29:59 piccolo kernel: DVB: registering frontend 0 (Zarlink  
MT352 DVB-T)...
Jul 10 19:29:59 piccolo kernel: dvb-usb: Hanftek UMT-010 DVB-T USB2.0  
successfully initialized and connected.

The device seems to be accessible somehow, if I do a "scan file" with  
file being a file with some frequencies in it, the red LED will be  
lit and it seems to scan - but it never finds anything.

So I got a channels.conf from a friend and tried:
georg at piccolo:~$ sudo tzap -r RTL

using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
tuning to 538000000 Hz
video pid 0x01b1, audio pid 0x01b2
status 00 | signal ffb7 | snr 0000 | ber 00000000 | unc 00000000 |
status 00 | signal ff00 | snr 0000 | ber 00000000 | unc 00000000 |
status 00 | signal ff00 | snr 0000 | ber 00000000 | unc 00000000 |
status 00 | signal ff00 | snr 0000 | ber 00000000 | unc 00000000 |


I then booted Windows and tried the Windows driver for the HanfTek  
UMT-010: Same effect, seems to work, but no channel will be found,  
but the red LED is lit.

The next step was to run the original software from the included CD  
(which looks very similar to the Hanftek software) and then warm boot  
into linux.

Is it worth opening the device and see which chips are in there (and  
no longer being able to give it back)? Or has anyone already done that?

How are the chances then to make it work, given that the Hanftek  
Firmware doesn't seem to work correctly?
Should I perhaps try to patch the dvb driver to make it accept the  
new USB ID? Can it work at all with the Windows firmware, i.e. is the  
protocol the firmware and the driver "talk" standardized?
