Great way to power your usb hubs if your pc can not handle it. Some hubs with not work with this setup, so try at your own risk.  Lot of people do this with the usb hubs, but I wanted to be able to use the hub without having to have the power attached.

And now to put it to use. We plan to use our with the network printer that can also be used as a scanner. the network printer box does not support network scanning.  We do not want to move the printer around.  Hence the cable is valuable for that. You still need a regular USB cable to connect to the printer.

Step 5: Usb power from the wall.

Super thanks!
What is the maximum length of the USB cable I can extend?
Computothought (author)  arifiosoneri2 years ago
You probably want to make it as short as possible. In any case it will depend of the what kind of power comes from the power supply and the resistance of the cables to the usb ports. I have seen some systems support longer cables and others that did not.
