I'm glad to help you, here are some solutions you can try. 

  1. Adjust your settings.  Finder > Settings > Sidebar > Turn on External Disks. 
  2. Reboot your Mac then reconnect the USB.
  3. Force your USB in the Activity Monitor.
  4. Check your Mac software update. Apple menu > System Settings > General > Software Update.
  5. Reset the NVRAM/PRAM. Shut down your Mac, then press the keys Command, Option, R, and P for 20 seconds until you see the Apple logo.
  1. If these can't help you, maybe you should consider a new USB to replace it.
