Re: 2 Questions

Ah ok, then maybe some JNI action would make my day... how is it interfacing with the camera? I mean how hard would it be to interface with the camera directly from Java without JNI?

Re: SOLVED: USB hub "recursive" power loop

Apparently others are running their RPi's in this config. with the red cable intact without issues, but what does the official USB spec. say about this? This is the way most users will run their RPi's in a productive state (24/7) so you should have an official statement for this! Edit: I'm talking "...

SPI port e-ink screen

It would be awesome if the next official peripheral from the foundation was a SPI port e-ink screen that worked straight out of the box!

Then with USB-3G and USB-bluetooth mouse+keyboard and the camera you have a complete solution!

Re: USB hub "recursive" power loop

Ok, thx, hard to search for this "thing".

But is this a _must_ or do the hubs work anyway?

I don't mind some power loss, I just don't wan't the hub or the RPi to break.

I guess better safe than sorry, also I hope the updated schema above is correct?

UNSOLVED: USB hub "recursive" power loop

Hey, so I would like to use this hub: http://www.exsys.ch/images/ex-1166HMV.jpg To both power the RPi _and_ then use this as the USB hub for the RPi itself to other devices.
