In my log, I see following message:kernel: usb 1-1.6: USB disconnect, device number 5acpid:  input device has been disconnected, fd 7acpid:  input device has been disconnected, fd 8I have not unplugged my USB keyboard, nor any other USB device. Why then, is the USB disconnecting automatically?The reason why it bothers me is, I am using grsecurity with deny_new_usb enabled. Once USB device is unplugged, it cannot be plugged in again. And this is exacly what I see in my log. The next line after the 3 lines mentioned above is:kernel: grsec: denied insert of new USB deviceAs I said, I have not touched the USB cable. Apparently the USB keyboard automatically disconnects/reconnects. But the reconnect is denied and I end up with no keyboard, leaving me the only option to reset my PC with the button.Why is this happening?Is there any way to prevent this?IS this some bug in the USB keyboard, or is it kernel issue ?
USB keyboard is disconecting automatically (without being unplugged)
