What about this one, guys? [[ The " DING " sound, then nothing happens ]]

Hello everyone,,

I came again with another USB flash drive that need to be fixed, when I plug it in PC, I hear the sound that takes places after plugging any USB device, But it doesn't appear in My Computer. This is a pic from the Device Manager:

And I can see that in ChipGenius_v4_00_0022_RC3:

I tried many SMI applications, It can't be seen be all of them as shown in this pic:

If it requires a hardware solution, Please explain it step by step, because I am not good at hardware.
I am waiting for your suggestions and ready to present more information or pic about the flash if you need that.

THANKS in advance.

problem with SMI Factory Driver; please Help!

I would create cd-rom on ufd SM3257ENAA. I face to a error and ufd couldn't recognize normally. In device manager it detected but had not drive letter. So, I use «SMI Factory Driver» with [VID = 090C PID = 1000]. After that, SMI MPTool could detect it using «Factory Driver and Hub» option. I began to flashing but it still on Testing. I would stop flashing, so i use «quit» button and then un-plug ufd. after re-plug windows detect it with SMI Factory Drive but SMI MPTool hang when I pressing «Scan USB (F5)».
I try on another windows but is same.
There is any way to revival ufd?

Долго не мог найти, а были так нужны в тот момент. Все найденные версии и документация, которая подходит ко всем утилитам. Итог, правда, не самый лучший — данных так и не вернул, от флешки осталась только половина, скорость тоже ощутимо упала, может, у Вас получиться лучше.

Удачи всем в восстановлении.
