You should contact the authors of it for any help you need with it, as no one else that I know of can even build that code, let alone run it. It's also marked to be removed from the kernel source tree in a release or so, so if you are using it, please work with the developers to get it cleaned up and moved to the proper location in the kernel source tree (out of drivers/staging/) so that the whole community can help out with it. thanks, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
