Your Chromebook may sometimes fail to recognize external USB devices. When you connect a USB flash drive to your laptop, you may get a strange error that says ChromeOS could not recognize the device. You can try switching to a different port and check if you notice any improvements. If the error persists, head below for more information on how to fix it.
Fix: External Storage Device Could Not Be Recognized on ChromeOS
Check the Format
Keep in mind that ChromeOS only works with FAT32, exFAT, or EXT file systems. This means that your USB drive won’t mount if it’s formatted using NTFS. If this is the case, format it again using a ChromeOS-compatible format.
Check If Your USB Drive Is Faulty
Your USB drive itself could be faulty. Connect it to a different computer and check if it’s detected and fully functional. If the same USB drive works on other machines, this may indicate your Chromebook’s ports are faulty. On the other hand, if the device doesn’t work on different machines, you may need to get a new one.
Check for Updates
Make sure you’re running the latest ChromeOS version on your laptop. Suppose the OS itself is affected by some strange bugs that break the USB functionality. In that case, chances are Google may have already rolled out a hotfix.
Connect your Chromebook to Wi-Fi and go to Settings. Then click on About Chrome OS, and hit the Check for updates button. Equally important, don’t forget to restart your laptop after installing the latest ChromeOS version.

I tried all three methods but my Chromebook still won’t recognize the USB cord and so it can’t find my scanner

I’ve done everything you’ve mentioned, but nothing worked. I’ve tried several thumb drives, in both ports, but it’s not recognizing anything. (all of these previously worked on this laptop, and drives were visible) For the last few weeks, I’ve constantly been troubleshooting, but Nothing shows up in my Files…and when I go into the Chromebook Recovery Utility, “no USB drives or SD cards found” is all I get in both creating a recovery, and erasing recovery.

Thank you!!! The reset + power button trick worked for me. When I would plug in the 2xhdmi->usbc adapter, the configuration of plugged in devices would make or break the setup on the first shot, and replugging did nothing. This allowed me to get a fresh start and I have 3 functioning displays now. Thanks!
