Bought a usb c adapter but cannot read a usb flashdrive

Greetings Hipacds,

Is the format compatible with macOS? File system formats available in Disk Utility on Mac

If the format is compatible, does the drive show in System Information? If a USB device doesn’t work with Mac

• "Verify that the device appears in System Information: On your Mac, choose Apple menu  > About This Mac. In the overview that appears, click the System Report button.
• In the window that appears, see if the USB device is listed below Hardware in the list on the left. If the device appears but does not work, review the device’s documentation for further troubleshooting steps."

Kind regards.
