Hi @jimmysofat6864 ,
Check that the USB port’s power is not being turned off.
Go to ''Device Manager > Universal Serial Bus Controllers > right click Root Hub > Properties > Power Management'' and check that the option “Allow the computer to turn off this device to save power” has been ''unchecked''.
To get to Device Manager, press the Win key + x key (both together) and click on the Device Manager link
I don’t know which root hub is associated with the right USB port, so you will have to check all of them.
Here’s an image from my PC just to show what I mean. It is slightly different as I have a different PC, so different hardware but for the USB Root Hub entries, the principle is the same.

If still no good you may have to replace the card or the connecting cable and check if that resolves the problem.
Search online for ''04X1089'' to find suppliers of the card w/cable that suit you best.
Here’s the [https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/s431_hmm_en_0c11084_02.pdf|hardware maintenance manual] for the laptop. Go to p.82 to view the ''necessary pre-requisite steps'' and then the procedure to remove/replace the Audio, HDMI, and USB card (aka ''IO port sub card'')
