I have seemed to have fried my NP2.
When I plug in usb, the voltages drop over 5 v rail (no reading) and 3 v rail (2.2v).
If I unplug the usb cable and plug in an external power supply (7.5v) the readings is 5v and 3.3v respectively.
The device does not show up in the devices and printers list, nor in STDFu tester and DFuSe demonstration.
Any thing I can do or is it ready for the bin?
