Hi,
Have you tried uninstalling/reinstalling the USB driver? Are you using a SD card to USB adapter? Here are some troubleshooting steps that may help.
- First uninstall/reinstall the USB drivers.
- Go to Device Manager and uninstall the USB driver.
- Reboot the laptop once the driver has been installed and it should automatically install after the reboot.
- If it will still not work, do try the other USB ports and see if it will work.
- If you're using the card reader port of the laptop itself, uninstall/reinstall the card reader driver from Device Manager.
- Once the card reader driver has been uninstalled, download and install the latest card reader driver from the manufacturer site of the laptop.
- Reboot your laptop again once the driver has been installed and see if it will work or not.
