En concreto, a la que se hace referencia aquí
"There are 60+ USB wifi adapters available on the market based on the ZyDAS ZD1211 chip" [...] "This driver is based on ZyDAS's own GPL driver available from www.zydas.com.tw. ZyDAS engineers have been responsive and supportive of our efforts, so thumbs up to them. Additionally, the firmware is redistributable and they have provided device specs"
Ni tengo que decir que si tengo que comprarme un dispositivo wifi buscaré uno que use un chip de estos.
