The jumper is right next to the psu plug, and it can be set to "VDC" or "VUSB". My programmer only works with VUSB.
When I use my 800mA 12V PSU, the programmer is not detected by software.
now abour power led ? (orange one on mine)
when i plug external psu it will lit brightly (on usb power its only dimmed)
maybe you can look on pcb if that plug is actually connected to something.
one example with another plug:
bought a KVM from ebay, where it states it can be powered from keyboard pwr, or from external 9v adapter. i need it only for switching vga inputs, so ive connected external psu and ... nothing happens

so ive disassembled it and there is a missing voltage regulator, there are traces, even silkscreen for it, but no trace of solder, nor regulator

ove soldered 7805 there and it works!

those chinese workers probably just want to cutdown price as "nobody will use it with externa psu anyway"
hope its readable as im writing a sh*t, littlre drung, and my selflearned english from games and manuals isnt always clear 8)
