Please try these troubleshooting steps:

1. Disconnect the hub from your laptop and unplug all connected devices. Wait at least 5 minutes, then reboot your laptop and reconnect the hub to see if the issue is resolved.

2. Check if the SD card has a write-protect switch. If so, slide the switch to the unlocked position.

3. Test the SD or MicroSD card with a different device, or try a different card in the hub.

4. Make sure the card is fully inserted into the slot.
