OK - ...It seems to get into a state where where I can only get it back to working is by turning it off then on. I'm sure there is an easier way but that works Looking at "top" there doesn't seem to be any funny USB named programs running... I must be doing something wrong with USB control or this may be a bug? but the only way to reset it is to power it off and then back on. Is this normal or are we getting closer to something. TIA C
