humm, not really :-/ Are you sure em28xx/device get loaded when your
device is plugged?

A good test:

- unplug your device
- dmesg -c  (clear the dmesg)
- plug your device
- check your dmesg, see if there is any error or message and please
send to us the output.
- lsmod could help also.
- if it's ok, load the i2c modules

What's the message of rewirte_eeprom.pl? The same as Throsten?

@Thorsten, in my case never needed to load modprobed i2c-smbus also.
That's why rewrite_eeprom failed to you, the script is not looking
to load this module. Thanks for the feedback.

Cheers
Douglas
