I am having trouble finding the driver for my card reader. It is an Emachines ET1331G-03W running Windows 7 Ultimate 64-bit. I have looked on the support site to try and find them but it is not there. The numbers i put into google bring up the card reader but only places that it is sold. The numbers on the card reader mount are Acer CR.10400.076. There are some numbers on the card reader board...9490B20621 and TB24616E.
As you say, they don't have a Windows 7 64-bit driver for the card reader, so I suggest you buy an external card reader which plugs into a USB port. The driver for all external card readers is included with Windows.
