My edu09 don't work

hi,
i finished welding my oscilloscope, but it doesn’t work. the led runs when I conect the oscilloscope to my pc but nothing else.
please can anyone help me

here I put some pictures

thanks for your help

is the usb cable not faulty?
With a quick look it seems your solderings are OK and the diodes are mounted correctly.
Can you give some more photo’s form the solder side?
Taken from the side.
Did you also tried to resolder the USB connector?

I asked the guy who sold me, and he say that the oscilloscope looks ok.
maybe is the firmware, or one component that is broken
What should I do?

We’ve had a look again at your pictures and couldn’t find an fault.
Please return your edu09 to your local dealer so he/she can send it to our repair department.
