I've noticed a USB hub on the 7dayshop's web site that sounds as if it would be perfect for my sister. But it says "NB Bus powered only". How will I know if it will be OK for her system?
Bus powered means it will need the juice from your machine ie: not powered from an external source.Unlike "self-powered" when they have their own power supply
Only buy a self-powered hub if you want to avoid problems.
thanks very much.
