Hi

 

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?

 

Thank you

Wilhelm

Did some further tests.

 

If I plug the usb cable in without holding the button down (for bootloader mode), the voltages are normal (4.89v and 3.3 v)

 

How can I test if the usb is working properly?
