Okay, I'm dense tonight because I've read your comment several times
and I'm not really sure I'm understanding it correctly. I don't
physically have a USB hub. I am wanting to purchase a USB hub. Prices
here vary from under $10 for a 4-port un-powered "laptop" hub to the
lowest $42 4-port powered hub. There will never be a situation where
I use the 4-port hub to power more than one device. (If I needed to
do that at some point in the future, one of my external hard drives
has a built-in firewire/USB hub I could use, if I could stand having
it powered up with its incredibly loud fan. Unless the power is on to
this device, the built-in hub doesn't work.) I'm wanting to have
permanent USB cables attached to all the devices so I can stop
swapping the one cable I'm using. I would also prefer not to have a
powered hub *if I don't need it* because the one I had years ago (USB
1.1) was always powered on unless I physically unplugged it.
I've googled galore and not found an answer. Maybe the simplest way
to ask is, if I am using a USB hub for only one device, does the USB
hub act as a pass-through cable extender so that it need not be
powered? Is there enough power coming from the internal USB port to
continue through the hub to the USB device, or is there a drop in
power through the hub that needs to be boosted by external power to
the hub?
Hope this helps
