instead of having each HUB have 7 buffers, which can eat up space.  We have each main object contribute currently one string buffer, which than when we initialize a Device_t we try to allocate one for it, likewise we release it when the Device is released.

Hopefully less memory needed.

Also updated such that the HIDInput classes can not retrieve these strings.

Changed test program to now also have list of HIDInput objects and when I detect a new one, I again print out info on it...
