Anybody ever replace the usb jack soldered onto the pcb of a made in china unit?
I'm about to embark on a usb type B replacement, after I found the unit I had traded as part of a cash/trade deal had the inside of the jack broken off (still pissed).
It's a maschine MKI, if anyone has a word to the wise |

I don't know the internals of a Maschine, but there are several ways to desolder the USB port.
The conventional DIY methods are solder wick or a desoldering pump or a combination of both (whatever works best). Using flux and perhaps also new solder to get the solder on the pads melting. And sufficient temperature.
But multi-pin component desoldering can be frustrating and bitchy. "IF" there is enough free room and you have a very steady grip, you can also try to dremel away the component at the legs and desolder these one by one afterwards, which is much easier. But this method has a very high risk to damage the board by accident, and there has to be enough physical space to do this.
The most elegant way is to use a hot air solder station and use adhesive metal foil. Tape the surrounding space/components with the foil, it will protect them from heat, and then desolder with the hot air, pulling out the component with tweezers as soon as all solder points are hot enough.

Hot air is the only "safer" and most efficient way to remove SMT IME. Stressing pads and putting too much direct heat can definitely lift a pad or trace. Might take it and as someone at a tech shop to pull it. Putting it back down is easy, just flux the pads of the PCB and socket.

Mu USB jacks came in. 4 pins and a few grounding joint spots. I hope it is easy. My euphonic artist control is still in the pits after the screen broke while changing the faceplate, because the internal screen bracket is a poor design. The little rubber buttons were all individual as well. Not fun. Can't get another screen except for-parts eBay listings.
With that said I have a ton of parts for the avid artist line now...
I don't want to have the same thing happen to this machine!

So I did it, it worked and I was able to demo and confirm everything is golden! WAY easier to service than Avid's artist series. That thing is a nightmare.
