Hi, all :<br><br><br>
Today my laptop shows the following messages during booting:<br>
<br>
udevb[478]: add_to_rules: unknown key &#39;ATTRS{idProduct}&#39;<br>
udevb[478]: add_to_rules: unknown key &#39;ATTRS{idVendor}&#39;<br>.....<br>.....<br>....<br>
<br>
These many  lines are repeated over and over filling the whole screen. <br>But
 after a few seconds booting continues as usual and the system works 
fine.<br><br><br>
But what is it with this messages, what does it mean  and how do i get 
rid of it?<br><br><br>Thanks ~<br><br> <br>
