I am using Ubuntu Mate 16.04.3 64 bit. What is this error:

usb 2-2.1: device descriptor read/64, error -110 ??

Someone says its a power issue, but I have nothing connected other than the keyboard & mouse.

In the dmesg, it appears: [ 36.261350] usb 2-1.1: device descriptor read/64, error -110
but then it reads this:
[ 41.666958] usb 2-1.1: New USB device found, idVendor=0cf3, idProduct=e005
[ 41.666962] usb 2-1.1: New USB device strings: Mfr=0, Product=0, SerialNumber=0

I too receive similar messages - have been for over a year. I spent hours at first trying to diagnose the meaning and cause with no success. I finally gave up and just accept them as a strange anomaly. I shut my laptop down daily - about 50% of the time there are no messages. My laptop functions perfectly once booted.
