i recently bought a E4440A PSA Analyzer , the previous owner had purchased a Option 111 USB Upgrade kit for the analyzer, the USB board, a USB Cable as well as a metal plate to cover the board were in a box and i installed them however the USB doesnt seem to work and i cant see option 111 in the option list when i check !
Is there a code word or a FW upgrade needed to enable this ?  i know that on newer models USB is standart but this unit pre dates those , i looked in the box and paperwork but there is no certificate that contains any enable code !
The serial# of the unit is MY45305016 , any help would be appreciated
