Sony VAIO USB port inoperable

Sony VAIO model SVP112A1CL with Windows 10 has two 3.0 USB ports.  One works and the other does not.  The message basically says that the flash drive is not recognized.  We know that the drive is OK.  Is there anything you can suggest to test this inoperable USB port?

If you know the USB port is inoperable (that is anything you connect to the other port works, but nothing works out the bad port) then it may be defective.

Try running System File Checker to see if that restores the port. Open cmd.exe with Run as Administrator and run SFC /SCANNOW twice. Allow to complete, shut down (power off), start up and test.

Go to BIOS and disable these ports. Boot into Windows and check if they are really disabled. Then go again into BIOS and enable them. Check if anything changed in Windows.
You can remove all USB drivers and install the new ones (latest ones) to see if it helps. If not - then it is a hardware defect and you can do nothing with it.
BTW, if you connect USB mouse or keyboard to this USB port - will it work?
>>  The message basically says that the flash drive is not recognized   <<  i assume you hear the recognition sound? then it senses a device is connected
also - tell me if the messages pops up when connecting the device

you can always look for something blocking the connection in the port itself - paper, glue - or bent connector parts

I will try all of your suggestions but unfortunately, the computer in question is headed to Belize for a week.  It is my daughter-in-law's system and she is a surgeon headed down there to assist on a volunteer basis for a week.  Please hold for about 10 days for me to test your comments.  Thanks.
