[olug] problems with external USB device

[Mr Scsi]

MIne is a dual connector. While it is 'bus powered', it uses 2 ports to do
this. One strictly for power, the other for data.

As far as power, the indicator light says it is powered and working, but on
this particular class of machine no data.
I have even tried plugging the power connector into an adjacent machine and
just the data into the subject machine, still no dice.
