I can't see SD Card connected to PC

[#1]

Hi,

I have Xperia Sola with microSD Kingston 16Gb class 10.

The problem is that when connecting to a computer, I see only the built-in memory ("Internal Storage"), but dont see SD card anywhere (Windows 7 x64)

In Device Manager on my PC i see device "Mass storage" (VID_0FCE&PID_A173) with yellow triangle (it means drivers not found, i google it but find nothing), perhaps this is reason?

At the same time i can see this card on phone via Settings - Memory and via Astro File manager (the card is showed as ext_card)

What do you advise that I could see SD Card via PC? (sd card must be inserted into xperia sola )

Thank you

Ok, i download SUS, run it and perform all steps (include firmware update).

The situation the same: in Device Manager i see unknown device "Mass Storage" with sony VID,

and still to idea where to find driver for this device.

In Explorer on PC i see device "XPERIA sola" with Internal Storage (i think this is MTP protocol)

I think main question is where to find drivers for Mass Storage device.

Any ideas?

Thank you

With this drivers device "Mass Storage" automatically recognized as

"Sony Ericsson sa0104 ADB Interface Driver"

Try to reboot PC and reconnect phone, but still cannot see any cards except Internal Storage.

Also i try to enable "USB Debug" option in phone Settings, my PC search for drivers and find all except "Mass Storage" (it once again present in Device Manager as unknown device).

If i disable the USB Debug option, "Mass Storage" not visible in Device Manager.
