At the worse case, just use libusb, that works on all of those operating systems you referred to. Again, just write to the filesystem from userspace, no kernel driver needed at all. Don't make it much harder than it really needs to be :) good luck, 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
