Which micro are we talking about?
Micro PCB
or Ardusimple f9p micro?
Post a picture of what you have! because your last post about TTL USB points to different problems.
If we are talking about Micro PCB then use the other slot for f9p micro (and then the other usb socket for it too)
Other people have experienced problems with the soldering of USB sockets on micro PCB
Edit: after configuring F9P, then move it to correct socket again.
