Q: personal hotspot don't work with USB

Try everything listed here, first:  https://support.apple.com/en-us/HT203302

Then, if your wi-fi hotspot connection works after those steps, but your USB tether still doesn't, then try reinstalling iTunes.

(There's a file installed/updated with iTunes that affects USB ethernet (such as hotspot) connections from the iPhone. Reinstalling iTunes replaces/updates that file.)
