device drawing too much power on a mini
 

Getting the following on my mac:

... DisplayLink Information.zip attached. Summary of system:
- Mac Mini (late 2009)
- running 10.6.9
- I've tried connecting directly to the mac, as well as via a powered USB hub - neither seem to work.
- monitor is in portrait mode
- performance seems fine (I do a lot of text editing, so not graphically intensive)
- I've tried various cables & USB ports - no change in outcome :-(

... ideas ?

OK, changing 2 things seems to have bought quite a lot on this front:

• I used a different USB hub
• I downloaded the 1.7 driver from http://www.displaylink.com/support/mac_downloads.html (I was originally using the 2.0 driver)

... I'm on hour #4 without the above error :-)

As an aside: my mini can apparently drive a lot more power than the standard dictates ( http://support.apple.com/kb/HT4049 ), so why Apple feels the need to shut down the device is beyond me completely ...
