I need to hook up a older PS\/2 keyboard to a usb port on the laptop docking station at work . this cable be not the cheapest but have good review , so I bite the bullet and go for it . the keyboard I be use be a Dell sk-8110 . in the top right hand corner of the keyboard there be 3 light label Num Lock , Caps Lock and Scroll Lock . at seemingly random interval and for no apparently obvious reason , all 3 light blink and my keystroke at that instant be not echo to the screen . it be kind of annoying , so just be aware that this cable do work , but may experience the same behavior as I be get . Buyer beware . Hope that help . happy computing !
