Asus laptop card reader stopped working

[JesseM]

I have had my ASUS G51VX laptop for a couple years now and it's still going strong. However, just recently the built-in SD card reader has stopped reading cards for some reason. When I pop in a card Windows will make the sound that a USB device has been plugged in and then a couple seconds later it will make the unplugged sound. The "Removable Storage Device" does not show up in Computer. I've tried looking through the Device Manager to find the card reader and re-install the driver, but I can't seem to find it anywhere. I suppose it is one of the USB controllers. I've also tried multiple SD cards so I know it's not the card.

Anyone have any ideas? Thanks!

Don't know If this will help, but I had a similar problem with my laptop (not ASUS though). I tried everything, ended up re-installing windows, which fixed it.

Thanks for the response, xcylent, however it has randomly started working again without me doing anything. I suspect there was some dust in the reader or something.
