A mouse and keyboard problem (randomly lose keystrokes)

[Alfonso García <alfon.gz@gmail.com>]

Hi, I experience a mouse and keyboard strange behavior since debian 7 to 8
update. Sometimes, when X windows system started, the USB mouse doesn't work
and the USB keyboard loses randomly groups of keystrokes. This not happen
ever and sometimes every works fine

This happened some of you before?

I'm not sure if this is a problem of the X edev driver or the udev device
manager

Note: When this happen, unplug and plug again the USB mouse connector fix
the mouse problem. Not so with the keyboard, which continues to lose
keystrokes randomly

I'm desperate :_(

Thanks in advance
