You could try to rmmod i2c-viapro and eeprom drivers. Then you can tweak the bit-delay of i2c-bus in bttv-if.c, udelay: 16. This gives a maximum speed of 20kbps ( 1 / 3*16E-6 ), and is slowed by interrupt service. It used to be udelay: 5. A minor patch for algo-bit was applied 2002/07/03, changing SCL behaviour, but I think it is not relevant here. I am not sure if linux-i2c list is no longer, so I'll post an experimental patch for algo-bit here with more details about the udelay parameter above. -- Kyösti Mälkki kmalkki@xxxxxxxxx
