Charge directly, not via hub..

Having an electronics background, I really should've realised this sooner - however - if you're using a USB data cable to charge your smartphone, and it seems to be taking forever - is it plugged into an unpowered, very cheap, USB hub?
Cheap USB Hub
"We need more power captain!"

Turns out mine was, and was taking about an hour for 1% of charge, because the power supplied by the hub is so little it was only just managing to supply more than the phone was using.

I plugged it directly into the USB port on the PC and it's gained 2% in 5 minutes.

Might be a useful tip, so figured I'd stick it on t'blog.

    Yeah, USB ports can only negotiate 500mA of current normally. Maybe one day we'll have non-cheapo USB hubs that can draw more so USB HDDs work on them.

    It's really irritating having to root around the back of the machine to plug an iPhone or USB HDD in, isn't it? Especially on a Mac Mini where there's plenty of room on the front for a single USB port.
