No, my tries integrating the codeaurora and the Google kernel tree led to many error messages. But Andrew de Quincey is working on the original linux gadget framework.

No, I'm as afraid as Andrew is. And my worst case power consumption is 2 A. I'm thinking about a portable 5 V power source with the National Semiconductor LMZ line.

This is what I did shortly after having posted here... But this is not enough as the compilation then fails.
So I made further updates in some source files and have managed to get the kernel and the modules finally compiling.
I'm now ready to test this but.... as I don't have yet the OTG cable, I will have to wait for it to arrive !
However in the mean time if someone is willing to test my 2.6.29 usb host kernel, I'll be happy to share it.

I'm also trying to make it work, and am waiting on the cables (I also ordered another one from Amazon, search for "Cables Unlimited USB Micro A Cable" , which I hope will work too).
A couple of questions: What is the dual-power cable for? Is it strictly necessary, or rather there for driving some of the more power-hungry devices?
Also, what would the APIs be for activating the N1's power supply? I'm sitting on a pile of N1s here at work, and I'd be happy to use one for testing that API I will be trying to connect a very low-consumption USB devices, so I'm hoping I could get away without an external power supply.

No unique hit. How about a link?

To power the upstream port, because the hub chip get its power from there.

Look for msm_hsusb_vbus_power in git://codeaurora.org/quic/kernel/bryanh/linux-2.6.31.y.git

Ooh, I see. The hub chip is not powered by the N1 itself?
Or would this also get activated with the power API call?

This won't fit, look at the photos.

Hmm, now that I realize that the dual power cable is strictly needed, I guess it makes sense that you'd need a female USB plug on that end. I was hoping I could go straight from the OTG micro-A to either a hub, or directly to the device.

Android on external monitor?

Would it be possible to run the android interface on an attached usb external monitor?

There are gender changers.

This one is more difficult: You need a Micro B plug.

At least it would be possible to mirror the phone screen by copying /dev/graphics/fb0 to /dev/graphics/fb1 periodically.
