Yes, I did it:
if ((ret = i2c->xfer(i2c, msg1, 2)) == 2) {
if ( strcmp(adapter->name, "Technotrend/Hauppauge Nova-USB") == 0 ) {
printk ("%s: setup for tuner BSBE1 (stv0299
synth) on TechnoTrend hardware S1810 \n", __FILE__);
return ALPS_BSBE1_TT;
}
However, this seems to fit to the old usb boxed as well?! Which would be
wrong.
They don't have a stv0299.
The problem is that stv0299.c does not know the stc version which would
be easier.
You could assemble the name string so that it contains the STC version.

The code has indeed en effect. If removing it even the 18 volt channels
dont tune
Have you tried to control the LNBP via it's i2c interface?
