What is that circular socket on USB hubs for? A power boost? By USB
hubs I mean the ones that turn one USB socket into four, etc.
I have two USB hubs, an Alcor Micro Hub, and a NEC HighSpeed Hub. Each
has a little round socket presumably for DC input. But no mention is
made about polarity and voltage, nor when one would need to give an
extra power boost.
There must be some standard. I suppose I can just connect the right
voltage wallwart to it? Wait, none of the standard adapters seem to
fit it. I suppose this is to prevent something stupid from occurring?
