You say that with the SD card in and the USB out and you are forcing a halt, you make an assumption that nothing is running. I would say your hub is getting hot because it's providing power to run the RPI and the internal power regulators are linear which produce heat. I also don't see how this relates to RPI test builds.
I would recommend you run through an ammeter between your hub and RPI and measure the current draw.
Well sure I have no idea what the software is doing to the hardware, so I'm posting about my problem in case someone can identify and fix it. I can't say if it's anything specific to the test builds or if it's just the standard firmware that's the problem at the moment. It would be useful to hear from others using hubs, whether theirs are getting hot as well.
I'm not assuming that nothing is running when I force a halt, only that XBMC isn't loaded at this point, so it's some part of the firmware/software that precedes that which appears to be the problem.
My hub doesn't provide backpower to the RPi, which I've confirmed by testing without the power to the GPIO and just the USB lead from the powered hub to the RPi.
