does the job,
This review is from: D-Link DUB-H7 7 - Port USB 2.0 Hub External (Electronics)
just plug it in and you are away.
* you must separate your USB devices into fast and slow. In my case fast includes external hard drive and webcam. slow includes mouse and keyboard. Only plug fast or slow devices into your hub. if you mix them, your slow devices will slow down your fast ones.
* it requires its own mains socket for power. (well it would - you can't get power for all 7 devices down the single cable that comes from your computer).

That shouldn't really be the case. I read you shouldn't connect USB 1 and 2 devices to the hub at the same time otherwise there are no issues with mixing.
But the host controller should assign a mode to your devices to decide how it will allocate the bandwidth, and a hub wouldn't change this.
Mouse and keyboard aren't slow, they just send sort of sparse data, so it it will get an 'interupt' mode, a web cams aren't fast but would get an 'isochronous' mode because it's a streaming device and the external HDD would get a 'bulk' data mode.
I've had no issues mixing these device types on it.
EDIT: lol I can admit when i'm wrong, the theory was right, but taking the mouse off my hub has made a difference.

Had no idea about mixing USB modes - thanks for the info.
