I purchased this Hub last December, to connect an eleven year old Epson
Stylus color 800 printer, a fairly new HP 5280 printer, an external hard drive, and cables for transferring photos from mobile phones and cameras to an HP6799 Pavilion Notebook (with Windows Vista).
When it arrived, I noticed that one light for one usb socket was not operating (hence, the four stars). However, the socket was working fine. I contacted Amazon and agreed with them on a small discount.
The hub comes complete with a usb cable to connect to a computer, and a power transfomer and cable. The hub can be powered by the notebook only. There was no need to install any additional software before using. I am pleased with the hub.
