[etherlab-users] Problem reading SII configuration from slave

[Jesper Smith]

Hello Andreas,

Unfortunatly the slave doesn't accept a new Eeprom (it accepts the data fine, 
but doesn't update anything). I'm trying to contact the manufacturer but they 
are hard to reach. Also, I suspect the Eeprom is 2048kb, but the data from the 
XML file takes 3072kb. 

How hard would it be to have Etherlab use XML files instead of reading the SII 
information? 

Best Regards,

Jesper
