Those are correct bridges. Not the defective short.
You can just clean the dirty(soldering flux). But do not open the bridge.

Does the PM39LV040*Vsop work now?

It may be the software related.
Can you try on the different software version?
Do you have another same type chip for testing?

Check the USB cable. Use another working good USB cable and see if it works.
