Using a NEC3520 and a LiteOn832 with Feurio. Both writers are not supported directly by Feurio. There is no update since Vesion1.68, dont know why.
So the only thing you can do is manually select your Writer.
Open the Feurio Writer, select Program, device list and select the writer you want to use.
Select device-info then go to driver and select "generic_mmc.dll" and mark select device as writer. You have also to mark cd-text override in preferences, otherwise you are not able to burn with cd-text.
Thats all, and your NEC writer should work.
Hope I could help, cause i`m a german and using Feurio german version, so I dont know if I translated all the buttons correctly.
