Does it see the phone? I haven't connected my phone in debugging mode but I know it works under W7x64 in normal usb mode.

If you are able to mount the SD the phone is connected to something... Let me get my OS out of test mode and see if it still connects. brb

 

Turn off USB debug if you have it on. The phone doesn't say anything in debug mode because it won't install drivers on the computer side with it on. I turned it off and it immediately gave me the option to mount the SD and when I did I instantly got the autoplay menu on the computer.

 

Tried a rear USB port?

 

Okay, when the phone connects does anything show up under Devices and Printers?

 

It is normal for nothing to show up when connected but not mounted. Curious why you aren't seeing the option to mount.

 

This problem is very common, I am too facing the same problem

 

I use windows 7 32 bit at home. I did not have to install any applications or drivers for it to mount my SD card. I do remember that I had to power off my phone and reseat the SD card once in order for it to give me the notification message. That only happened one time.

Under Settings - SD Card & Phone storage, you could try unmounting and remounting the SD card while its plugged into the PC to see if that makes a difference.

If nothing else.. do a factory data reset on your phone (which will wipe things.. keep in mind).. and try again without installing any 3rd party apps.

If the factory reset does not work you may just need to grab a replacement phone.

I would uninstall any app you installed to read the SD card. Windows 7 does not need anything to open your SD card from the moment.
