1) when powering your RPi from a monitor's USB port don't switch your monitor off and expect it to keep running.
[well actually longer story - I'm using a DELL widescreen monitor U2410 and was powering it from a blackberry cable I have a small keyboard, mouse and ethernet plugged in - no Hub - and it runs fine - I was ssh'ed into it and running scripts I use to check the status of several machines / processes here . I had to leave early switched monitor off and went , next morning came in and saw that the RPi was still powered up via the off monitor and doing it's stuff - however switching on the RPi power cycled the ports and reset the RPI.... ]
2) .... actually I'll post more later as I find them

Do you mean "switching on the Monitor power cycled the ports and reset the RPI"?

yes it ran fine all night logging the stuff it needed to do until I switched the monitor on in the morning I have re-created this this morning also via a ssh session ...

Does it also turn off if the monitor blanks and goes into low power mode?

Re: basic mistakes not to make
no - the power is constant to the USB ports then

Re: basic mistakes not to make
There is another easy mistake to make when using TightVNC Viewer to connect from a Windows PC to a Raspberry Pi. If you don't add a port number at the end of the remote host name, your connection will be refused if the default port isn't the same as the oner that your Raspi is expecting.
I have found that using 'raspberrypi::5901' gets things working.

Hi,
how do you manage to power RPi from a monitor's USB hub? I just bought Dell 1707 monitor with USB hub and the hub works only when the upstream usb cable from pc to monitor is connected. Since RPi must be on to power the upstream USB cable (to be detected by monitor to power the hub), there is no way to get it working this way.
So your monitor's hub is working without being connected to RPi usb port?
