Gameport to USB

I'm the owner of a old logitech wingman joystick, which runs on a old 15 pin gameport. Is it possible to convert the signal from the gameport to usb which then goes into the computer?

What, like this? http://www.trianglecables.com/usbtojoydbad.html?utm_source=usbtojoydbad&utm_medium=shopping%2Bengine&utm_campaign=FROOG&gclid=CIOS3P3p96kCFcbb4Aode3otXw

Plenty show up on a Google search.

Yes, like those adapters. But my problem is that my joystick is digital and not analog.
