There are two serious problems with USB microscopes for soldering:

1. Latency. Depending on your setup, latency ranges from moderate to
severe. Any latency at all will make soldering very difficult.

2. 2-D view. You need the 3D view provided by a stereo microscope or
a large glass lens for effective soldering.

About the only thing USB scopes are good for is inspection.
