I have an Asus F5N X50N-AP011C. I have manually installed Windows 7 x64 on it, replacing the original Windows Vista. It also automatically installed a card reader driver, but it can no longer read xD cards. The driver shows in the device manager as "Generic- xD/SDMMC/MS/Pro USB device" (under "drives" - and a drive is also shown in Windows Explorer). The same card reader once used to work with xD cards. I also tried to manually install drivers from this website: http://www.station-drivers.com/page/realtek.htm - the RTS 5158 but it didn't work (it shows as USB device in device manager, but not as a drive in Windows Explorer).

Does anyone know

  • what card reader my model has built-in? (I think it's the 5158 but I don't know how to verify that - there's also no hint in the System Information tool, only the driver name is listed under "drives")
  • how it is connected internally?
  • if there is a better Windows 7 x64 driver?

In Device Manager, check the Properties for the device. Under the Details tab, you should have drop-down options for Device ID, Hardware ID and such. Plug those into Google, and you should be able to find the proper model numbers and drivers you need.

Thanks, but the only info in there is the generic driver info from the Windows system driver. Nothing hardware specific. Device Class GUID = {4d36e967-e325-11ce-bfc1-08002be10318}, Hardware ID = USBSTOR\DiskGeneric-xD/SDMMC/MS/Pro_1.00 and similar. – Felix Dombek Mar 25 '11 at 19:30

You should always try the drivers provided by the manufacturer first, whether it be for the whole computer or individual hardware. I do not consider sites such as Station-Drivers to be reliable.

Asus's support website for the X50N provides the 2007.03.16 Windows Vista 32-bit update for the Realtek USB 2.0 Card Reader. If these drivers do not work, you could also try the latest Windows 7 64-bit drivers (2011.06.16) provided by Realtek.
