> that i already suggested but it appears his units have zeroed sub fields
if it has zero subfields it has no original eeprom but a modified one. 
all mikrotik cards with no exception have the subvendor and subdevice id 
set.
the subvendor and subdevice is is stored in the eeprom. or the eeprom 
could be also broke, but in this case the values should be 0xffff
i have several original mikrotik cards of this type and this is where i 
got these values from. are you sure that your card is no immitation?
can he send me a picture of this card?
