Re: USB Power

2011-01-14 Thread Christopher Chaltain
If one of the USB connections is only used for power, I wonder if one of 
those cheap AC to USB power connectors would work.

Hi List,
I have bought an external hard drive with no power supply, ie gets power
from lap top
It came with 2 USB connnections and I now know why
My machine I am plugging it into is old and is just being used for music but
has only one USB port.
The drive will not spin up on the power for one only and hence I cannot use
for this application.
Is there any small cheap USB power source i.e battery or even mains that I
can plug second USB into to increase power.
I have tested this on my powered USB hub for my main machine and it works
but that is overkill and more expensive than I would want to solve this
issue?
Thanks as alwayss
Colin

the problem he is running into is that type of drive uses the USB for both 
power and data transfer.
