Hello everyone! I saw this thread some months ago, but do not know how to properly reply to it. I have the same problem, and it's just not few messages - it was about 40k messages in 10 minutes. No functional of my USB device (which is CCID USB token) is broken, just enormous amount of spam in the logs. I'm on 4.12 kernel, but I've seen this error on 4.11 and 4.9. Could this problem be caused by a bug in e.g. libusb, not a device itself? -- 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
