Long shot... Anyone any experience with an #OmniKey AG #CardMan 5121 RFID reader?

We have one (in a printer) and worked find with #pcsclite before, but latest version does not work, gets "card is unpowered".

Yes, I have tried lots of suggestions from "the internet". At this point I may need to try and get hold of such a reader so I can work on it here (printer is at the office).

Only clue so far is pcscd debug shows it trying different voltages, which only makes sense for contact card.

Help!
