Disconnect/connect usb ports

[Jose Luis Rodriguez Garcia <joseyluis%gmail.com@localhost>]

Several times per day I receive disconnect and connect messages from
usb devices: mouse and keyboard (it is ps2 keyboard attached to a
usb/ps conversor).

Both disconnect at same time, and usually connect at few seconds at
same time (when they don't connect I have to reboot the pc).

This NetBSD 7.0 amd64 on a Pineview PC.

Any idea?
