I will try programming values 0xFF.
By the way, why should we set these timeout value?
I think, we don't have to change from default values (U1 Timeout = 0,
U2 Timeout= 0).


I think the default '0' is the same like '255' - disable power save? Where is the meaning of "default" defined in this case?

In the USB v3.0 specification it says that we shall not enable the U2 timeout for a downstream port that is connected to a HUB. Currently there is no check for that. We might want to add such a check.
