I bought this phone about 5 month ago, and after the update, I was trying to connect the phone to the computer. But the computer didn't have any notification about the USB connection. I reset my phone and go to the factory mode. I connect USB storage, I close the USB debugging, but my computer doesn't appear anything. I research it and I go to run->devmgmt.msc, but it doesn't really say about the USB device for my phone. I try to reinstall my phone USB driver, but it's not working... I'm lost now...

but it doesn't appear anything... I have no idea what's wrong with my phone... Please help!
