No USB connection to computer

Just noticed today when I plug in my phone to computer it is not showing up but when I test USB it says connected.
But still not charging on computer either.
Why is this software is Android 6.01.

Have you tried other ports?
Check the USB port for dust and see if it connects in safe mode

When I connect charger it works fine charging but nothing when I connect to 2 different Pcs.Using original Sony lead.
Plugged in another phone to pc works fine and connects.
