Compro has a lot of different cards with the same PCI subsystem (: And you are right, we can't make a difference to the T750 by that, since it also uses what is subsumed under the saa7133 chips. (saa7133/35/31e) Nothing left to detect than use some byte from the eeprom, even the not yet used board init for both is the same, might be different on the T750. > saa7130[0]: board init: gpio is 843f00 > saa7130[0]: i2c eeprom 00: 5b 18 00 c9 54 20 1c 00 43 43 a9 1c 55 d2 b2 92 > > saa7130[0]: i2c eeprom 10: 00 ff 86 0f ff 20 ff ff ff ff ff ff ff ff ff ff > > saa7130[0]: i2c eeprom 20: 01 40 01 02 02 01 03 01 08 ff 00 87 ff ff ff ff > > saa7130[0]: i2c eeprom 30: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > > saa7130[0]: i2c eeprom 40: ff d6 00 c0 86 1c 02 01 02 ff ff ff ff ff ff ff > > saa7130[0]: i2c eeprom 50: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff cb > > saa7130[0]: i2c eeprom 60: 30 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > > saa7130[0]: i2c eeprom 70: 00 00 00 10 03 9c ff ff ff ff ff ff ff ff ff ff > > saa7130[0]: i2c eeprom 80: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > > saa7130[0]: i2c eeprom 90: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > > saa7130[0]: i2c eeprom a0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > > saa7130[0]: i2c eeprom b0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > > saa7130[0]: i2c eeprom c0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > > saa7130[0]: i2c eeprom d0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > > saa7130[0]: i2c eeprom e0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff > > saa7130[0]: i2c eeprom f0: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff >From the Compro T750.

Tuner type is 0xd6 versus 0xd7 on the T750, also tuner address is 0xc0 versus 0xc4 and digital demod is 0x1c versus 0x1e. (not shifted >> 1) Igor received also a patch for remote support on the S350. Without looking into any further details yet, might me more to consider, but maybe that IR patch works on recent Compro cards like the T750 too.
