Thank you for being assisting me on this task Albert.
I've been exploring the files you mentioned and I'm a bit puzzled about 
this specific string: &dib0700_usb_id_table[32] (where 32 is the value 
for one of the cards). I couldn't find any correlation envolved with it. 
Is there any special place I should look at to get the proper value for 
this string?
Also, the last section seemed  the right one to add the entry for my 
device. Do you agree?
