Hi, I'm Pete. Welcome to JustAnswer! I'm reviewing your question now, and will post back with your reply ASAP.
Are you using a desktop PC or a laptop?
Can you see the phone appear as an external device when you go to "Computer"?
Are you using a desktop PC or a laptop computer?
Yes, do try a different cable.
Also try a different USB port on the computer.
There are 4 pins in the USB connection - 2 are used for charging and 2 are used for data transfer.
If the USB socket on the phone is partially clogged with dirt or lint, it can prevent the data connection from being made.
Please confirm what all drives and devices you can see when you go to "Computer"?
No, USB devices use a universal USB driver which comes on all PCs, so the computer should immediately recognize when a phone is connected unless there is a problem with the connection or the driver.
