Your Pre & Post RS Error counts are quite high.
In an ideal world they would be at zero and stay there. To zero them can you reboot the Hub using this method and then keep an eye on the counts.
Switch the Hub off using the small switch on the rear of the Hub next to the power cord and pull the PSU plug from the wall socket.
Give it a good 5 minutes put the plug back in and switch the Hub back on.
Allow the Hub a few minutes to fully restart then check the counts again in an hour or so.
