Updating sd car reader on pc
If you have a computer with front and back USB ports and the reader is connected to the front ports, try connecting the reader to the back USB ports.Make sure the USB connector is securely attached to the USB port.
A temporary workaround would be to connect the camera, phone, or another device to the computer using a USB cable with the SD card in the device.If the SD card does not work with your device (e.g., camera) and does not work with a computer or another card reader, the SD card may be bad.Skip to check write-protection to start troubleshooting SD card related issues.In most cases, Windows does automatically detect and install standard drivers, but some card readers may work better with drivers designed specifically for that device.If your USB card reader is capable of reading types of digital media cards, try reading a different card to test the reader.Sometimes this resets the connection and allows the device to work properly again and read the SD card.
Some USB card readers may have drivers available on the manufacturer's website.
If more than one card cannot be read, then the USB card reader may be defective and unable to read SD cards.
With some card readers, the SD card may have to be pressed in a little harder.
Some laptop computers and desktop computers have a built-in memory card reader.
It is possible the memory card reader is not working properly and not able to read the memory card.
To resolve this issue, close all open programs and allow your computer to idle for a few minutes.
