Hi,

Im trying to access the SD memory card through the mini usb header. I had used a jumper to short the pin 6-7 on the keypad header.
My PC( win 7 pro 64bit) will prompt out a GTT bulk-IO device as show in the pic.

Hi,

To check if the GTT70A is placed into mass storage mode, you should see the USB connector image on the display.
If you see the GTT startup image instead, this means that you have not successfully placed the GTT70A into mass storage mode.
Double check that your connections on pins 6 and 7 are marked as '5' and '1' on the keypad connector.

The GTT70A when in mass storage mode should show up as USB Mass Storage Device in Device Manager, and does not need any drivers.

I hope this helps.

Best Regards,
Raquel
