I had a brain fart.

I know what the usb host w/ power cable would look like. I have parts orderd for the host mode configuration. I hopefully await a hdmi/usb-host cable.

First off, thanks for this awesome discovery !

But I've still got some questions..
what is the difference between the usb host and the usb host w. charging?
And what should the universal charger do?
Thanks!

The USB host should be pretty much the same as the OEM dongle. The host with power should allow you to charge the unit when also attached to a power supply. I have not tested this but I expect should work without a problem. The reason people might just opt to not have the power is to make a smaller package.

The universal charge cable puts the unit into charge mode no matter what your 5VDC power source is. Without this, you must use the OEM charger (or aftermarket adapter) else get a red X over the battery.

Anyone know if it would be possible to hack a USB port into the multimedia-dock? It has the 30pin male and female.. probably passthru.. I've yet to take it apart (I suspect there are screws on the bottom). Anyhow I figure the dock should work with the USB adapter, so maybe all the wires are there inside the base. Then it would just be a matter of adding a female USB (with appropriate resistor). And possibly this would allow charging, audio, etc WITH USB attached. Best part is that multimedia docks are available at local bestbuy, etc.

alternatively, i'm considering a keyboard <sigh>.. but only if usb host mode works with it.

This dock is suppose to allow either the HDMI or the USB connector to plug in the back so that means it does pass all this through. This is going to be interesting....

okay a few questions again..

Would it be hard to make a usb keyboard work on the tab (like cutting up the usb cable and replacing it with a 30pin dock connector?)?

And how much effort would it take to create a hdmi out? or a normal video out if possible..? Because I actually need an old video out port but on the samsung site is says that the video out represented is not compatible with the 10.1..

and where do you solder everything on? I've yet to find a picture of the 30pin connector which tells you where to solder..
Where would I solder in this image? http://shop.kineteka.com/images/thumbs/0000564.jpeg
Or should I just get a tab-out like this:

If you want to take a USB keyboard and make it work, the easiest thing for a beginner would be to get the tab breakout connector and then solder the wires as shown in the diagram. If you don't have a female connector, you can cut off the male connector from the keyboard and just match up the colors.
Only get the other connector if you have a way to ohm out the pins so you know what is what, have a good soldering iron with a fine tip, and also have a steady hand. I got my connectors in the mail last night and I can probably take a picture and specify the pin layout if you like.

As for the HDMI, I am not sure yet. Seems like either no one has an adapter or if they do, don't want to share what the insides look like. For the older tab, it had one pin for standard video, but HDMI has 19 pins so either a lot of pins on the 30pin connector get reassigned in some way, or there might be some type of chip that does the conversion. I don't know enough about HDMI to make a proper assessment at this point. I hope someone with an actual adapter will chime in soon.
