How would I fix this in soldering it back, I'm not sure the pins for the mini-usb are long enough to get through the pin holes

First of all, use a solder sucker to get all the solder out of those holes. Then align the holes, solder them again and then carefully solder the lines in front, being careful not to short them together. The micro USB pins do not go all the way through the holes.
Good luck!

Same thing happened to me. I was able to attach the connector back to the PCB by soldering the 4 "legs" from the bottom of the PCB. However, that wasn't good enough because you also need to solder the tiny SMD pads on the back-side of the connector. As I don't feel comfortable soldering SMD stuff I had a friend do it for me.

Irritating for all of us. You just can't apply any significant torque to that USB connector. When we revised this board, we will go to a through hole device. More expensive, but worth it.

It's getting worse...while the the case of the connector now again sits firmly on the PCB and all SMD pads are perfectly soldered I observe a loose connection somewhere _inside_ the connector. USB is now completely unusable. So, I'll have to add a buck converter (-> bit.ly/2p1H1rz) and feed the device through GND&VCC of the FTDI connector. Sigh... |

Thanks for the spec link. I had been looking, unsuccessfully, high and low for that document earlier. It's good news that I can feed up to 20V to those pins and thus won't need the buck converter.

I'm now powering the system through Vin/GND on the FTDI connector - all is well. I cut off the micro USB plug and soldered two female dupont cables to the USB cable.
