NK3 Mini not detected anymore by OS

Hi,

my Nitrokey 3 Mini is not detected anymore (tried two different laptops).

  • nitropy nk3 list as root: nothing
  • gpg --card-status: nothing
  • dmesg: nothing

When I connect the device it very shortly blinks green and then shows a red LED (no blinking).
It worked in the past and I successfully upgraded to the latest firmware.

Might this be a hardware issue? (which would be really unfortunate as I own this thing now for about one week).

Any suggestions for debugging?

Best,

Support thinks it is a faulty NK.
