Description Jeff Robins 2017-07-17 09:27:30 CEST

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.

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
