Just a summary for the situation. Firstly you may want to see if you really want to use a generic HID device, in most cases, you can use a custom device and then use libusb0.sys or winusb.sys as the driver under Windows and then use pyusb with it.
Using a custom device will also make it possible to use pyusb under Mac OS X. Recent Mac OS X makes it very difficult (or impossible) to detach the kernel HID driver. In that case, it is not possible to use libusb (0.1 or 1.0) and thus pyusb with the device. So if you really want to use pyusb and care about cross-platfrom, then you should forget about generic HID device and use a custom device instead. If you really need to use HID device, there are a few options. 1) If you only cares about Linux, then you can use pyusb with no issues. libusb under Linux can detach the kernel HID driver. 2) If you only care about Windows, you may want to look at pywinusb. http://code.google.com/p/pywinusb/ 3) If you really want to use pyusb under Windows with the HID device, you can use libusb-win32 filter driver for that particular HID device. Please use the latest libusb-win32 for this purpose. And take note this is not a recommended solution. 4) If you want to have cross-platform support for the HID device, then you need to look at HIDAPI and use the python binding for it. Take note the python binding for HIDAPI is not mature yet. http://libusb.6.n5.nabble.com/Opinion-HID-and-Windows-back-end-td3716872.html http://comments.gmane.org/gmane.comp.python.pyusb.user/749 5) Another option under Windows is to use the HID branch of the libusb-pbatard git repo or older version of libusb-pbatard (up to pbr332). This is not recommended as the official stand of libusb-1.0 admin is not to support HID native backend under Windows. -- Xiaofan ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
