[Thunderbolt General] spider366:
Ok so here's the news on my end. With the dream kernel things seem much better! However I was watching my ma usage and it went from 48ma to 240ma something after turning on wifi. Then after turning wifi off it never dropped. I rebooted and things went back to a cool 48ma. I'm guessing my original problem was with the stock kernel. But now that I'm on the new one the phone wont power down the wifi or something and made me burn thru my bat till I rebooted. Any ideas gents? Reboot did fix but that usually kills a good 4 to 10% of my bat everytime. I have next to nothing running in the background too.
[Thunderbolt General] spider366:
Guess I should add that now after reboot I'm around 100 ma usage and steady with wifi on. Maybe a reboot once a day might do the trick till CM is finalized. Was thinking bout trying the mr2 radio stead of 2.5. Anyone know if there's a difference or advantage to either?

I was having trouble until i started using the KangBang kernel, that one seems to be the best for me
[Galaxy Tab 10.1 Android Development] pokey9000:
Problem, Samsung?

Recipe:

1 dock connector from Kineteka

2 10k ohm resistors - needs to be 20k, a single 22k is too much

1 donor USB extender cable

Various heat shrink, tape, etc to taste

Pinout here. With the connector plugged into the Tab, and the Tab oriented with the chat camera on top and the connector on bottom, pin 1 is to the left of the connector.

Chop off the plug end of the extender, separate out the wires, cut / strip / tin. Cut off the shield. Slide on the plastic shroud for the dock plug and a piece of heat shrink for strain relief. Don't forget this or you'll have to undo the whole thing (like I did). You might also want to cut thin heat shrink to go around each wire to protect it from shorting at the connector pins.

Solder the two resistors in series and put them between pins 13 and 15. This tells the Tab to go into OTG host mode. Be creative. Surface mount parts might be better here.

Solder:

ground (black) to pin 1

green (D+) to pin 3

white (D-) to pin 4

red (+5V) to pin 6

Test this out before shrinking the pins by plugging into the Tab along with a USB key. If it works, you should get the message above.

Once it works, put the connector shield, spring clip, and shroud on.

All said and done, this comes out to about half the price of the Samsung adapter, but at the expense of some elbow grease and potential unreliability. I expect clones will be showing up on eBay someday though, so if I've done anything useful here it's to entice our friends in China to start their assembly lines.
[Galaxy Tab 10.1 Android Development] mbh87:
Clean it up and start selling them imo.
[Galaxy Tab 10.1 Android Development] pokey9000:
Better?

Taken before I have to ugly it up with a bit of hot glue. The connector housing is too shallow to fit the resistors and make a good strain relief with heat shrink. I also noticed that the retainer ring that holds the housing together pops right off when you unplug the connector. A little super glue needs to go there too.

I'll give this a shot
[Galaxy Tab 10.1 Android Development] time_shock:
i'm hoping that the connector can allow you to utilise many of the pins at once.. i'm thinking of designing an all in one connector that has USB host/OTG connectivity and allows me to charge the device and still allows me to use HDMI/component video out
[Galaxy Tab 10.1 Android Development] used2hvatreo:
I will pay you infinity for that, give you my firstborn, whatever you want. But seriously, what use is a "media dock" if you can't charge while I are passing hdmi thru.

Back on topic, nice job OP, that is my new weekend project
[Galaxy Tab 10.1 Android Development] nemir:
Nice job.

Since I don't have a galaxy tab 10.1 . I have an idea :

Is it possible to use female female usb adapter for the GT ?

does any GT10.1 owner verify whether or not this method is working?
[Galaxy Tab 10.1 Android Development] pokey9000:
Nope, won't work. With this you won't get the 5V power from the tablet, and you won't have the resistor on the ID pin to tell it to go into OTG mode. I suppose you could provide your own 5V power to the device, and hack the kernel to force it into OTG. But that's probably as much trouble as building a cable anyway.
[Galaxy Tab 10.1 Android Development] ericlmccormick:
This is awesome! Do you know if it will handle only one item at a time or could you hook a hub to it and run like a hard drive and keyboard at the same time?
[Galaxy Tab 10.1 Android Development] pokey9000:
Haven't tried a hub yet, but I'll do so when I get home later. The Transformer has multiple ports on its dock so presumably that should be ok. There is a power budget limit though, since I got a dock warning about overcurrent when I tried a USB powered hard drive. A powered hub might fix that.
[Galaxy Tab 10.1 Android Development] ericlmccormick:
If you create a cable that charges the Tab while using it in host mode, you could probably pull the power off the charging cable instead of from the accessory pin.

If doing that, might want a selector switch or diode to keep current from flowing into the accessory pin.

I ordered a few of the 30pin connectors yesterday and I am starting my designing now for my "docking station". I am trying to figure out if I will have 1 or 4 USBs on it.
[Galaxy Tab 10.1 Android Development] dsh897:
Omg thankyou so much, I've been waiting for this. i was missing the two 10 ohm resistors!!!!!

Already cut up a USB and galaxy cable trying this..

will try this when i get home. im at work. let you know what i find
[Galaxy Tab 10.1 Android Development] joedoe:
Why you didn't you use one 20K 2% ohm resistor instead of two 10K ohm?
[Galaxy Tab 10.1 Android Development] pokey9000:
I didn't have a 20k resistor on hand, and 20k isn't a common value in smaller resistor kits. The most readily available values in the 10k range are usually 10k, 22k, and 47k.
[Galaxy Tab 10.1 Android Development] pokey9000:
Sure enough, with a powered hub I can hook up a USB stick, a USB powered hard drive, and a mouse. I tried a USB audio adapter as well as a 360 wireless controller via the PC USB wireless adapter, both were unrecognized. I think I remember hearing that the latter was explicitly unsupported, though I figured I'd try.

Disks show up in /sdcard/usbstorage/sda /sdb ... for as many drives as you plug in.
[Galaxy Tab 10.1 Android Development] used2hvatreo:
So does HDMI share any of the same pins as the USB? I ask because I am gonna piece together a hub and then add an HDMI cable to that, and then plug that into the media dock, and then it will be a true dock. Just need to get power for charging involved in that mix

[Galaxy Tab 10.1 Android Development] dsh897:
Probably not, as the unit doesn't have enough power to supply it and if it did it would drain your battery quickly.

Easist way is to get a powered hub. Or one of those two male / 1 female cords where you can supply power from an alternative souce.

[Galaxy Tab 10.1 Android Development] snaai8:
Solder the two resistors in series and put them between pins 13 and 15. This tells the Tab to go into OTG host mode. Be creative. Surface mount parts might be better here.

Do you solder the two resistors together at pin 14 or do you solder them on the space between pin 13 and 14 and the place between 14 and 15?

Sorry for all these questions, I just want to make sure I don't screw up at my first try!

[Galaxy Tab 10.1 Android Development] pokey9000:
0402 is 1mm, and the even/odd pins are on .75mm centers. So the metal endcaps should sit right on the pins if you lay a single 20k resistor between 13 and 15.

[Galaxy Tab 10.1 Android Development] addisonhammer:
Are you talking about the original, smaller Tab running Froyo?

USB Host capabilities were added in Honeycomb 3.1... so with a stock kernel, it definitely wont work until you get the upgrade.

Get a custom kernel that has been compiled from source with USB host included... and you may have some a chance.

Check out the android sdk for info on capabilities and features in the different platforms (Froyo = 2.2, Gingerbread = 2.3.x, Honeycomb = 3.x)
[Galaxy Tab 10.1 Android Development] pokey9000:
People have been doing USB host on Nexus One, Nook Color, and other platforms for quite some time.
[Galaxy Tab 10.1 Android Development] addisonhammer:
With custom kernels... yes.

Since the kernel is linux-based... hardware libraries can be added and compiled into custom kernels. It wasn't till Android 3.1 that native support for USB host was offered.

My point wasn't that it's impossible, just that plugging a cable in wasn't going to do the trick. I'll edit my post to reflect that.

[Galaxy Tab 10.1 Android Development] Maui:
Do you know what the pin setting of the original Tablet-to-Host cabling is? Thinking about building an USB connector for the Open Accessory (which can be supported by a little kernel tweaking). Since the Accessory plays the host-part the cabling would be just like the one when you connect to a regular PC.
[Galaxy Tab 10.1 Android Development] pokey9000:
Looking at my charge cable, the sense pins aren't even hooked up. Mine looks like it has D+(3)/D-(4) to data lines, V_BUS_1 (7,8) to +5V VBUS, and GND (15,16,30) to ground. Why not just use an off-the-shelf USB cable and chop it up if needs be? You can find them cheaper shipped on eBay than the price of the bare connector.
[Galaxy Tab 10.1 Android Development] ericlmccormick:
In order to have host capabilities you also need access to pin 13 to tell the unit to be in host mode and to pin 6 to power your accessory. Check out my post on how to make your own cable (http://xdaforums.com/showthread.php?t=1155065)
[Galaxy Tab 10.1 Android Development] pokey9000:
I'm quite aware of how to enable host mode...

The GP was asking about Android Open Accessory, where the accessory runs in host mode.
[Galaxy Tab 10.1 Android Development] toxicchicken:
I'm working on making one of these, my first attempt worked until most of the pins broke, but i've been looking at the PDMI standard, and noticed that on a PDMI connector there is a second 5V source to power high current devices. doe anybody know if there is such a pin on the galaxy tab connector? I know that the connector has been modified away from the standard, but i was hoping that such a pin might exist.

There is an article on the PDMI interface on wikipedia.
[Galaxy Tab 10.1 Android Development] Facegarden:
You don't need to build a cable for Open Accessory, it uses the regular cable the unit comes with. It requires special devices designed to work that way, however. You absolutely cannot use the open accessory mode to plug in regular USB devices to your tablet.

And the real issue with Open Accessory is that the accessory must charge the tablet. So you can't really have battery powered accessories unless you have a very large battery (charging the tablet would kill the battery on the small unit). I was under the impression Open Accessory allowed small battery powered devices to be used with it, and was very disappointed when I found out that isn't possible.

[Galaxy Tab 10.1 Android Development] Facegarden:
Hmm. Maybe send them an e-mail and ask if they have any way of sending it to you? Its possible its not on their website but they could still do it.

But I've attached a picture showing the cable that came with my Tab. Note that only the pins needed are even present in the connector. You might be able to relocate a pin but it doubt it.

Really, you'll have to get the connector from the link in the first post, or wait till Samsung actually gets their damn connector available.

No, a 3G modem will not work. The USB keyboard and mouse will, and most likely will function fine even with a hub.

3G modems are finicky enough on a PC though, getting them to work with a tablet is unlikely at the moment. If you want to use one, I'd recommend getting a wifi hotspot version, or a cradlepoint portable wireless router instead.

I know this an old thread but i just wanted to point out a post in the "galaxy tab plus accessories" forum, since it seems to have accomplished exactly what the person above me was attempting to do. XDA member "emil_b" claims to have modified the multimedia dock to simultaneously do hdmi out, trickle charge the tab , & serve as usb host! In case some of u may not know, the same dock works with ALL tab variants(PERSONALLY ONLY TESTED WITH P1000, P7100, P6200, P6210 BUT 99% CERTAIN) so if this proves true, this should be shared with all the other tab forums in hopes that it can be made into an actual product.
