Hi experts!
I would like to ask for your help.
Accidentally I damaged the USB port of my
Rigol DG4162 function generator by shorting the
+ and - pins of the USB port.
Since then the USB port does not detect/read/write any USB stick and
there is now power on the +5V pin.
Does anyone of you have the circuit diagram of this device or
details on what exactly I need to check/ repair in order to
get the USB port fixed again?
Thank you in advance for your help!
Best regards
Rooky
