Please log in for more thread options Thanks Woody,
Power shows as 500ma so that should be OK.
I did notice that the power management option allowed the computer to
switch off the power to the root hub so maybe connecting the device was
too much of an instant power drain....maybe.....
It might also be that the USB external case is faulty. Unfortunately
difficult to know.
There is no external power capacity to the case but I will try tne
powered hub idea.
Cheers,
PC
