Description of problem: After upgrading from MGA5 -> 6, the keyboard has started dropping some characters and repeating some characters when typing. I don't see a pattern to the behavior and the same character may be dropped one moment and then repeated the next time hit it. This makes it very difficult to write a bug report. LOL. I think it is related to USB-3 support. I see many instances of "USB 3-2.2: reset low-speed USB device number 4 using xhci_hcd" when I run dmesg. I also see device number 7. My keyboard is device 4 and my mouse is device 7. As I was writing this my USB 3 hub flashed a few times and then powered down. I had to unplug it and then plug it back in. I moved the keyboard to a USB 2.0 port and it seems to work fine now. I'm still seeing reset messages about the mouse, which is now device 35. I have attached some output from dmesg How reproducible: Happens constantly for me Steps to Reproduce: 1.Plug low-speed keyboard into USB 3 port 2.Type, quickly seems to make it happen more often 3.
Created attachment 9497 [details] dmesg output showing USB 3 issues

Still happening with latest kernel (4.9.43-server-1)
(In reply to Jeff Robins from comment #2) > Still happening with latest kernel (4.9.43-server-1) does [physically] disconnecting and reconnecting these devices help? I have a similar problem here and use this workaround.

I unplugged them and then plugged them back in. It didn't make a difference. I seem to mostly notice it with the arrow keys on the keyboard.
This went away
