Major problem with libusb and HID device is the lack of HID backend under Mac OS X. Under Linux, libusb works fine with HID device (need to detach the kernel HID driver). Under Windows, there are some limitations as well. So HIDAPI is better in terms of cross-platform support. -- Xiaofan ------------------------------------------------------------------------------ Is your legacy SCM system holding you back?
