[ydl-gen] Boot error

[angelo]

Dear Derick, thank you very much for the quick reply. The fact is that I 
previously used the same USB keyboard and USB mouse and I hadn't any 
problem, it recognizes the keyboard saying the model and it uses a 
standard driver common for all mice. The problem arose only after the 
blackout. Another peculiarity is that I connect both keyboard and mouse 
to a USB hub in port 1, in order to have a USB port free for something 
else. Greetings, Angelo.
