When your Chromebook does not recognize your USB drive, first confirm that the drive is not faulty and check its file format.
If you are using a USB hub, try unplugging the hub and plugging the USB drive directly into your Chromebook.
To confirm if the USB port on your Chromebook is faulty, unplug the USB stick from the current port and try plugging it into a different port or different computer.
If it connects, the USB port on your Chromebook is the culprit.
If the USB drive is not recognized on any other computer, it’s probably dead and needs to be replaced.
