My plans are to add support for this type of weather station to an existing open source weather server, wview. The software runs on a variety of *nix operating systems and I would like to take an approach that is most standard and more likely to work on many *nix systems. The sofware also runs on SBC computers like NLSU, Sheeva plug, etc.
Therefore my goal should be to take the aproach that will be more likely to work on any *nix system. So far I see that there are several options: * user space solution: libusb + libhid * hidraw driver API I suppose that most *nix have this driver loaded on the kernel. What I don't understand is what you suggest about the possibility of writting a backend for libhid using hidraw driver. * usbserial I don't know much about this option and I don't know if this specific device can run using this driver. Data is received through an interrupt but it seems that the reset command is transfered using control_data, not a write interrupt.
