[ltp] T40p, usb detection failed

[Ulrich Kuehn]

Hi,

Sounds like a problem my system currently also has. Well, sometimes,
sometimes not. My research in google produced some interesting results,
namely that there might be a kind of hardware fault. Some people advise
to get the main board replaced. It seems to be a rather well-known
problem of the T4x series.

Below I put some links where such a problem is discussed. 
Hope you are still within warranty..

Ulrich
