https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235625 Bug ID: 235625 Summary: Repeated excessive logging about unsuccessful port reset during device enumeration Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: usb Assignee: usb@FreeBSD.org Reporter: maxsteciuk@gmail.com Since FreeBSD 12 build around last summer it was noticed the syslog was flooded with the following messages >>>Jan 29 20:18:44 kernel: uhub_reattach_port: giving up port reset - device vanished Although the log message is displayed the USB devices and hubs are functional: successfully connected and working. The following sysctl configuration helps to get rid of excessive logging but the downside that certain USB devices (e.g. Create SoundBlaster) are not even getting recognized by USB hub controller. >>>hw.usb.disable_enumeration=1 As a quick solution I decreased log level for the message from 0 to 1 so that at least to reduce log noise. Here is a small proposed patch for decreasing log level: https://github.com/trueos/trueos/pull/283/files As a more elaborate solution I was thinking about possibility to implement log throttling for this warning so it logs a suficient number of times to bring to attention but not inifinitely. Another question is whether this is a symptom of a larger problem: is something broken (e.g. sys/dev/usb/usb_hub.c , /sys/dev/usb_device.c) or not functioning as expected...
