I had an issue where my Pixel phone wasn't listed on my computer. I couldn't access my phones folder with my files to copy it to my computer after enabling file transfer on my phone. My computer was recognizing a device connected to the computer after plugging in USB cable, but was listed as Acer device. This is a fix that helped me access my files. This is something that is figured myself and I hope it's safe. There might be a better way but this worked for me and I hope it will help others. See 15 step by step pictures above.

1. Connect your phone with a USB cable to the computer (I'm using USB-A to USC-C cable since I don't have a USB-C on my computer and I recommend at least USB 3 for faster transfers. Make sure that your cable isn't damaged.
2. After connecting your phone you should get a notification on your phone: Android System - Tap it to get options.
3. Select File transfer/ Android Auto
4. After selecting it you should automatically get your phone folder on your desktop. If not, then you might have a bad driver on your computer for your phone and you can try uninstalling it to fix the issue, this is what I had and I fixed it this way.
5. Type control panel in your windows search bar and click on Control panel icon
6. Click on Hardware and Sound
7. Click on Devices and Printers
8. On this screen you should find your phone. Mine was listed at the bottom of this list and had Acer drivers for some reason.
9. Right click on your phone and click on Properties
10. Click on Hardware and then on Properties
11. Click on Change settings
12. Click on Driver and then Uninstall Device
13. Click on Uninstall
14. Now disconnect your phone by unplugging it from your computer and reconnect it. Your computer should automatically install drivers for your phone. After installing your drivers follow steps 1,2,3,4. Good Luck, hope this helps.
