Why powered?
Because motherboard USB ports are limited to 100ma current draw at
computer startup. Then once they reach 93% of rated voltage the limit
goes to 500ma. Maximum power draw for any one port is 2.25 watts. With
an unpowered hub all connected devices share the current/power limit.
Get a powered hub and the seven or eight devices hanging off the hub are
guaranteed not to overload the USB port.

Why powered? None of mine are. Well, maybe due to USB3 ports :-)

Do any of you have a recommendation of a good, RF quiet powered hub? Are
there any to avoid? It would be great to be able to power it from the
shack
12 VDC supply rather than have yet another power brick. In the
absence of
any info, I'm looking at an Anker 7 port powered hub that is powered
from a
12 VDC adapter.
Thanks and 73, Jim, KY2D
