Dear all,

To be able to detect USB devices after system startup one has to compile 
"device ehci" into kernel along with "device ohci" or "device uhci". 
Actually it may work without EHCI for a while (as it was with me), but 
further there is no guarantee.

There is no string "device ehci" even in GENERIC kernel, so I guess one 
should be kept aware of turning this feature on either by some notice or by 
including that string into GENERIC configuration file in future releases.

Sincerely,
Eugene Rogoza
