Public bug reported:

Binary package hint: xkeyboard-config

I have usb keyboard Genius KKB-2050HS with the usb hub. 
When I press the caps lock, scroll lock or num lock keys, my system hangs and my keyboard is not working. When I reconnect my keyboard, everything works nice. Then if I press this keys again, this problem repeated.
When I disabled the keyboard's leds, this problem was solved. But I had to abandon the indicators.

How to disable keyboard leds:
I edit  /usr/share/X11/xkb/compat/ledcaps file:
<code>
default partial xkb_compatibility "caps_lock"   {
   indicator "Caps Lock" {
       !allowExplicit;
       whichModState= Locked;
       modifiers= None;
   };
};

partial xkb_compatibility "group_lock"   {
   indicator "Caps Lock" {
	whichModState= Locked;
       modifiers= None;
   };
};

partial xkb_compatibility "shift_lock"   {
   indicator "Caps Lock" {
       whichModState= Locked;
       modifiers= None;
   };
};
</code>


/usr/share/X11/xkb/compat/lednum
<code>
default partial xkb_compatibility "num_lock"   {
    indicator "Num Lock" {
       !allowExplicit;
       whichModState= Locked;
       modifiers= None;
   };
};

partial xkb_compatibility "group_lock"   {
   indicator "Num Lock" {
       modifiers= None;
       whichModState= None;
   };
};

partial xkb_compatibility "shift_lock"   {
   indicator "Num Lock" {
       whichModState= Locked;
       modifiers= None;
   };
};
</code>


/usr/share/X11/xkb/compat/ledscroll 
<code>
default partial xkb_compatibility "scroll_lock"   {
   indicator "Scroll Lock" {
       allowExplicit;
       whichModState= Locked;
       modifiers= None;
   };
};

partial xkb_compatibility "group_lock"   {
   indicator "Scroll Lock" {
       whichModState= Locked;
       modifiers= None;
   };
};

partial xkb_compatibility "shift_lock"   {
   indicator "Scroll Lock" {
       whichModState= Locked;
       modifiers= None;
   };
};
</code>

And reconnect keyboard.
