No, while this thread has kinda stalled and I don't have any time to fab anything of my own, I just used the Galaxy tab (original) dock with the Tab 10.1 dock tray, and that gives me my charging plus HDMI out.

Hi guys,

Since I've used info from this topic I feel like I should post also here my achievements .
I've successfully modified my tab 8.9 original dock to add USB host and AC charge to it.

Here is the Tab 8.9 topic: http://forum.xda-developers.com/show....php?t=1610832
Currently rocking:
Z1 compact - Stock
Nexus 4 - 16GB - Stock 4.4.2 + xposed
LG G Pad 8.3 - Stock + xposed
In-house: Nexus 7 - 32GB - (Stock 4.4.2 - rooted), RAZR i (stock 4.1.2 - rooted), Defy (MIUI) + Galaxy Tab 8.9 (ICS stock- rooted)

But none the less, I did received my UD and at least I have the 10.1" slider into which the tab can fit. I will connect this to the new 7" True HDMI dock I also ordered. Wasting money??, well, I'll limit my amount of StarBucks coffees and make up for it.

That was besides the point Have anyone every opened the Dock (7" or useless 10.1") too see what is inside? I got as far as removing the four screws from the bottom on my UD (useless dock) and probably need to pray it open a bit. But have not gotten that far yet, before I started typing ('cause I did a search with not any applicable results) - next time someone is going to bitch at me again for 'have you tried search????' - I'm gonna tell them to let the forum know to get a better search engine - one that actually works. - Again, off the topic. (LOL)

My whole idea is the make the "Ultimate Multimedia Dock" (**** Samsung for selling everything separately if they darn well know it could be one device!) I especially need a SD-card reader (since I sit now with two 32GB cards and a 10.1" tab that cannot read them!)
My idea is to add a USB surface mount female plug inside the dock (after I prayed it open, I will get picks and let you know if it will work) - Something like this.
Slimmer if I can get one - still needs to shop around a bit more. If anyone knows of anything slimmer than the above one let me know, please.

But that is not what I need help with so much..... According to this thread, one can create your own USB Host dongle. I want to build that into the dock.
So that means that whatever the connectors are between the two 30-pin connectors of the dock, needs to be intercepted with the USB connector (pins 1,3,4 &6) and the 20K resistor between 13 & 15.
The idea is mainly to have access to the USB female port as a card reader, while the tab is on the dock and maybe while the charger is connected. I am not so much interested to use the USB port while the HDMI is playing (modding the 7" dock). I would hate to send my 50" TV up in smoke - or the tab for that matter, if both devices are both connected and does not like being together......

Anyone have some diagrams or experience to help figure this out - it is highly appreciated.

Thanks guys & gals!
Ever made this dock? sounds freaking awesome!
