Linux driver since 2005. Read http://linuxtv.org/pipermail/linux-dvb/2005-November/006081.html The drivers are now stable, and work well on reasonably current 2.6. kernels (certainly 2.6.24 upwards).
The current linuxtv.org-modules support DiSEqC. But some DiSEqC configuration can have problem with current overload at startup. Solution can be this patch
- Early drivers had issues with current overload on the tone generator. Read http://www.linuxtv.org/pipermail/linux-dvb/2006-November/014567.html.
- Version of the v4l-dvb driver around linux 2.6.22-14 kernel fail on (dvb)scan.
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' initial transponder 10773000 H 22000000 5 >>> tune to: 10773:h:0:22000 WARNING: >>> tuning failed!!! >>> tune to: 10773:h:0:22000 (tuning failed) WARNING: >>> tuning failed!!! ERROR: initial tuning failed dumping lists (0 services) Done.
This bug is now fixed and the driver works.
- Some versions of the card seem prone to what appears to be hardware failure breaking control of the tone generator from the DVB frontend IC. Work-around patches are available that (at least for some cards) restores basic tone+voltage DISEQC signally sufficient for simple configurations.
