ztex is a firmware Kit with a corresponding Driver API which is especially designed for the ZTEX Modules but which should work with all other EZ-USB based hardware. The Firmware Kit is written in C and assembled using a powerful macro processor. This allows you to specify all required settings using by a few commands. The necessary USB descriptors and the descriptor handling routines are generated automatically. The package runs under Linux and Windows (porting to other operating systems should be no problem). The Java driver API allows the development of platform-independent device drivers.
