Why the HP Envy x360 SD Card Reader Stops Working

The HP Envy x360 15 uses a Realtek USB card reader chipset (often RTS5227 or RTS5260). Windows 11 cumulative updates sometimes remove third-party storage drivers when rebuilding the driver stack, leaving the reader invisible in Device Manager or listed as an unknown device with error code 28 or 43.

• Windows 11 update silently removes Realtek Card Reader driver
• Device Manager shows yellow exclamation under Memory Technology Devices
• SD card not detected in File Explorer after sleep or restart
• Error Code 28: drivers not installed, or Code 43: device failure

Fix 1 – Reinstall Realtek Card Reader Driver from HP Support

Go to support.hp.com/us-en/drivers, enter your laptop model number, and download the latest Realtek Card Reader driver for Windows 11. Before installing, open Device Manager (Win + X), expand Memory Technology Devices, right-click the Realtek device, and select Uninstall device. Check the box to delete the driver software, restart, then run the downloaded installer.

Steps to Reinstall

1. Press Win + X and open Device Manager
2. Expand Memory Technology Devices or Universal Serial Bus controllers
3. Right-click Realtek PCIE CardReader – select Uninstall device
4. Restart laptop, then install driver from HP Support
5. Restart again and test SD card

Fix 2 – Update Driver via Windows Update Optional Updates

Press Win + I, go to Windows Update, click Advanced options, then Optional Updates. Under Driver updates, look for Realtek or HP Card Reader updates and install them. This method uses Microsoft-signed drivers which are stable for Windows 11.

Fix 3 – Check Registry WriteProtect Setting

Open Registry Editor (regedit) and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies. Check the WriteProtect value – if it is set to 1, change it to 0 and restart. A WriteProtect value of 1 blocks all removable storage devices including SD cards.

Fix 4 – Run Hardware and Devices Troubleshooter

Open Command Prompt as administrator and run: msdt.exe -id DeviceDiagnostic. The Hardware and Devices troubleshooter will scan for missing drivers and device errors, and attempt automatic fixes. After it completes, restart and insert the SD card again.
