      Okay, then it's easy, I've another slug at home, with an usb stick too (it has been there for more than one year!). I'll try this evening :)

      I'm surprised of this failure. Is there any visual clue the PSU has fried if I disassemble it?
      Is it repairable?

      Many thanks.

      PS: rofl, with a colleague we just tried to load the psu with a small value resistor and measured the voltage. it was enough powerful to fry a 0.25 watt 3.3 ohm resistor ( ^_^ ) but now I get the christmas tree led sequence even with no usb device attached :)
      We fried the psu even more :)

      The final anwer will come this evening :)

      Moreover I just grabbed a 3A 5V psu from an old unused device. Just have to adapt the right connector :)

      Yeah, this is similar behaviour I had last year --- PSU failure, AFAICT.
      (The PSU can't quite handle the extra load of the device and the voltage
      drops just far enough to deeply confuse the NSLU2's power circuitry.)

      It's worth trying to find another 5V power supply and seeing if that
      fixes it.
