Hi !
I've modified the sources of a 2.6.29 kernel to try to have my
Terratec Hybrid usb key working in DVB-T mode.
Basically I modified em28xx-cards.c, and used the settings of a WINTV
HVR-900 for my card.
[EM2882_BOARD_TERRATEC_HYBRID_XS] = {
.name = "Terratec Hybrid XS (em2882)",
.valid = EM28XX_BOARD_NOT_VALIDATED,
.tuner_type = TUNER_XC2028,
.tuner_gpio = default_tuner_gpio,
//.mts_firmware = 1, with or without same results
.has_dvb = 1,
.dvb_gpio = hauppauge_wintv_hvr_900_digital,
It nearly works: only the 1st tuning works, then that's as if the
tuner is locked up.
For example scan, tunes properly for the 1st frequency:
--------------------
# scan /usr/share/dvb/dvb-t/fr-Metz
scanning /usr/share/dvb/dvb-t/fr-Metz
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

--------------------
If I change the 1st freq in the config file and restart scan it works.
So only the 1st tuning works when the FE is opened only one time,
after the firmware is sent:
-------------------

-------------------
How could I solve this stupid tuning problem ?
(BTW, this usb device seems to work properly in analog mode)
