The original post was 5 years ago and the last before yours was a year ago. Could be the driver you need is a different version. The model number of yours is difficult to make out, doesn't appear to follow the format of the ones I have, e.g. L655-S5153 PSK2CU-0Q101U, makes it difficult to obtain accurate results in a search.

I know that this thread is TOOOOO old but i don't know where else i can make that question.

Does anyone has any clues how to find out the correct drivers for that device because already try programs like drivers genius, driver magician e.t.c. and nothing.
