Please somebody help me

... I'm strugling for this card to work for centuries.
I have the following in my kernel:
Code:
<*> I2C support
│ │ <*> I2C device interface
│ │ --- I2C bit-banging interfaces
│ │ <*> I2C PCF 8584 interfaces
│ │ <*> I2C PCA 9564 interfaces
<*> Video For Linux
│ │ <*> Conexant 2388x (bt878 successor) support
│ │ <*> Add support for additional audio chipsets
and this is some output:
Code:
