I'm thinking of developing a host driver for the realtek wifi dongles (search RTL8188CUS on ebay for example) as a low cost way of adding a low-cost, bare metal wifi alternative for Kinetis applications. Use the Freescale Host USB stack? Is this feasible? I'm thinking of sharing it or making it open source if anyone else is interested in this project. For my own application, I'd install the dongle inside the enclosure. Feedback?
