Freecom DVB-T USB Stick Revision 4 (RTL2831U chipset)

[ugm6hr]

This is a new thread for Freecom DVB-T USB stick (Rev 4) owners.

A Linux driver exists for the Hardy kernel as discussed in the Archives - quoted below.

I'm toying with the idea of upgrading to Hardy now. Does this still work with the final Hardy?

PS: Has anyone tried the AMD64 Hardy with this?

EDIT: The rapidshare link doesn't work - try the German forum link for download: http://forum.ubuntuusers.de/download/9970/

CONFIRMED:
This works just fine in Hardy 64-bit

In the uncompressed folder - just:

make
sudo make install

This is a new thread for further discussion - specifically with regard to anyone who has had success with the new Intrepid kernel.

If I try to compile and install it under ubuntu 8.10 (64 bit), the stick isn't recognised after installation. I hoped the driver for this stick would be integrated in the 8.10 kernel but this isn't obviously the case...

greetz,
Willi

Shame. Looks like I'll be sticking with Hardy for the foreseeable future then.

As for the kernel integration of the driver - I can't see much discussion about development of that since the original driver was released.

Hey all,

This is what dmesg gives me when I connect my conceptronic dvb-t usb stick:

Anyone who can make something from it?

Thanks,

[bas.doodeman]

Got it working in Intrepid.

1. Open the attachment.
2. Extract it.
3. make
4. sudo make install

The source in the archive is based on: rtl2831u_dvb-usb_v0.0.2mod.tar.gz

I have updated the following files with the sources from 2.6.27-7 as explained in Doc/Readmeubuntu.txt:
demux.h
dmxdev.h
dvb_demux.h
dvbdev.h
dvb_frontend.h
dvb_net.h
dvb-pll.h
dvb_ringbuffer.h
dvb-usb.h
dvb-usb-ids.h

I could not find the source of dvbt_demod_base.h, and I have left the original from 2.6.22-14 in place.

After this I have updated rtd2830u.c as follows:
1. inserted the line

DVB_DEFINE_MOD_OPT_ADAPTER_NR(adapter_nr);

after

MODULE_PARM_DESC(debug, "set debugging level (1=info,xfer=2 (or-able))." DVB_USB_DEBUG_STATUS);

2. changed

if (dvb_usb_device_init(intf,&rtd2831u_properties,THI S_MODULE,NULL) == 0 ||
dvb_usb_device_init(intf,&haihua_properties,THIS_M ODULE,NULL) == 0 )

to

if (dvb_usb_device_init(intf,&rtd2831u_properties,THI S_MODULE,NULL,adapter_nr) == 0 ||
dvb_usb_device_init(intf,&haihua_properties,THIS_M ODULE,NULL,adapter_nr) == 0 )

That seemed to do the trick. Everything compiles with the usual warnings.

[WILLI]

Hey,

I want to thank you, this works like a charm!!

Thank you,
Willi

[ralle_b1]

Thanks a lot, bas.doodeman


Your fix workes on my system.

One remark: I first overread the line "the fix is based on..." and downloaded the wrong file, which didn't worked in intrepid of course. Reading carefully helps. So a Warning: For intrepid: Download the file at the end of Bas post!

Thanks again, Ralle

[ranjo]

Thank you! This fix works great. I can tune and watch using Xine. I tried using mythtv as well but that isn't working. Could this be a failure of the driver or is it mythtv?

How do you use xine? I use me-tv (which has an xine base), but it is very slow. Kaffeine is better (but KDE based).

And will xine record?

[ranjo]

Thanks for your help!

Mythtv was my problem, when scanning channels it makes mistakes with filling the database correctly. The transport frequencies weren't filled in or were wrong. Now it's working perfectly and I can record four channels at the same time (from the same frequency). So this cheap usb device is working great! I hope that these drivers will be added into the linux kernel, that would make my mythtv box working without compiling anything
