Ah, nice, yeah must be a 'short switch' I was considering soldering one up, but that cable would make it a lot neater, shame, I hate waiting for things and everything I want is from China :p

Hello All.

I've just seen this thread.. Don't know how I've missed it!!

A nice little hack. It's similar to what's known as "back powering". With this, a powered hub sends power to the host device.
It's against the USB specifications, but if it works.. great!

Some of the Raspberry Pi guys use this to save a connection. There were a few USB hubs available that supported this "out of the box", but they seem to be quite scarce now. It's viewed as a way of potentially bypassing circuit protection. I don't think that this really applies here as the same socket is used for data and "both ways" power.

Yep. I did that on my first 256MB pi - I used a 99p ebay hub, it worked pretty well after getting rid of the polyfuses on the pi usb ports. Before that you couldn't feed enough power through to avoid lockups.
