A friend has a problem with his card reader in it does not recognise any cards, yet the USB socket works ok.
I changed the card reader for a second hand one I had spare and also a brand new one, all have the same problem. The card readers work ok on my machine.
On the MB are three header sets of pins and tried all three, but still have the problem.
NOW, here's the strange thing: If I try to format the SD card W7 says it's in use (why?) but format anyway. I say ok and it formats. I can rename the card name and copy files - no problem - BUT as soon as the computer is rebooted the original problem comes back.
There are no drivers missing in the hardware list. tried uninstalling and reboot but no change.
Any ideas guys? It's completely baffled me!
