That's great. But, the biggest problem with the skeleton driver is that it is not really needed anymore. Very rarely do we need to ever write a new USB driver these days. Things like a "USB logging daemon" using bulk endpoints can be easier to write in userspace using libusb, and have it work on all operating systems. Kernel USB drivers are a rare thing for brand new types of devices anymore, which is nice. good luck with your driver, 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
