Why do you think VID:PID is ignored? You have entered different
VID:PID in the configuration than I have provided.

default_programmer = "diamex-avr-usb";
programmer
  id    = "diamex-avr-usb";
  desc  = "Diamex AVR USB Programmer";
  type  =  "stk500v2";
  connection_type = usb;
  usbvid     = 0x16c0;
  usbpid     = 0x2a9b;
;

You need to provide VID:PID of Your Diamex interface that is
VID=0x16c0 PID=0x2a9b. Your configuration contains VID=0x03eb
PID=0x2104 this is why interface cannot be found. Please copy-paste
exactly as provided above.

Where I know VID:PID of your interface? From previous message.
