Did I buy the adapter, because I throw away my PS / 2 keyboard is not the same, and would save 10. The tip of a review, above, I have followed and installed the latest driver of the keyboard. But Hatt brought nothing. :( The keyboard is unfortunately too old !!! This means that the adapter has a USB keyboard in my opinion is not to gebrauchen.Habe but then bought. Could have flaps yes at 1.50 cost. ;) Therefore, I can give a star just because of the price and free delivery.
