Re: NOT SOLVED: USB hub "recursive" power loop

So I cut the red cable and this doesn NOT work. The PI does not detect the hub. Or rather the light next to the usb ports (@drgeoff on the hub) don't even light up... none of them. The red wire IS the power, I have tried it to make sure. And the hub is detected fine if I use a regular upstream cable...

Re: Foundation Camera Board information

One thing though, can you make the band narrower and slim so it can squeeze out from pibow case above the ethernet plug? The band fits, it's just that the camera port is a couple of millimeters unaligned to the ethernet port. How could you guys miss that?! So you have to squew the cable somewhat, b...

low res + high fps

Code: Select all

raspivid -o video.h264 -t 20000 -vf -hf -fps 90 -w 640 -h 350
Works for me; I have the camera upsidedown (-vf -hf).
Then just play in VLC and press [ and ] to control speed... seems to work!
It's a bit blurry, but it's night here so I'll try again tomorrow.

Re: a quick performance comparison of java on raspbian

Given the maturity of our Java port to ARM and the Java toolchain, and the speed advantage over Python it would IMHO be good for everyone if Java had a more prominent place in the RPi community. Exactly! Also it would be great if Oracle could organize a appserver competition on the RPi, since it al...

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?
