problem with SMI Factory Driver; please Help!

Hi
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?
