Hi,

I've been plugging away blindly trying to get my Leadtek Winfast DTV1000S card working
While trying to figure out how to find the gpio for the tda10048 to be recognised, I have come across an unknown device using the i2c tools. 
Can anyone shed some light as to what this device is? 

...noting that the tuner is at 0xC0 and the eeprom is at 0xA0 on the same bus

the i2cdump is as follows:

No size specified (using byte-data access)
