A similar question has been asked on modaco but I don't think a solution was found. Therefore I am going to ask if this would work here.
Is it possible to connect a micro usb (male) to mini usb (female) adapter up to this thing (HTC 4 in 1 adapter: I can't post link because I am a new user but just search it on youtube). This would connect to the tg01 micro usb and provide a 3.5 mm audio out in addition to a mini usb connection where one could potentially hook up a charger. I was thinking of testing this out as it would cost about 10-15 dollars but I do not want to damage my phone in the process. I have no electrical engineering knowledge but maybe someone else can explain if this would work before I order anything.
On a side note: I order samsung WEP870 bluetooth headphones on sale as an alternative to this. Note sure how sound quality is but I will try answer any questions you guys might have.
Any input is welcome.

I was heavily involved in the discussion running on MoDaCo you refered to; unfortunately there has been no breakthrough on this issue to date.
I did look into the the HTC adapter you mention, but it actually uses the proprietary HTC ExtUSB plug on the input end (connecting to the phone) and NOT a normal mini-USB. The ExtUSB has 11 pins which include a discrete audio output (being used to feed the 3.5mm jack socket) and also hard-wired power (used to accept the charger input).
In the case of the TG01 uUSB socket, it is too 'intelligent' for its own good. Every function, charging, audio out, USB data transfer, etc., is under procesor control. Different functions are triggered by the device 'seeing' a certain resistance across the sense pin and ground; depending on this the processor then configures the use of the socket pins accordingly.
I am after what you are trying to achieve also; there is a chip supposedly available which is intended to fulfil exactly this functionality, but I've been unable to find any devices on the market which use it and attempts to contact the manufacturer with a view to getting a few samples to try and build an interface have so far been unsuccessful.
I've attached a couple of documents which explain the uUSB Charger Adapter and also the chip spec sheet for reference.

If anyone else knows anything to help move this one forward, will be much appreciated !
Thanks for the nice explanation,
Hopefully one day there will be an adapter that can make this possible.
So, I purchases a USB OTG cable in an attempt to try and expand the functionality of Webtop while using Nebtop. I've been unable to get any response from the phone when I plug in this cable. I've tried my wireless Logitech mouse and keyboard that worked off the bat with my TF101 using the Unifying remote they came with as well as an external TB drive.
Has anyone else had any experience with this? It seems logical that the phone supports host mode since the actual dock has 3 full sized USB ports.
All the information pertaining to this sort of thing I've come up with seems extremely phone specific but if there's a simple solution I'm missing thanks all the more.

The problem actually lies in the usb port of the phone itself. The dock was designed for this purpose, and the dock app handles most that for you, the one thing that the dock is able to do that a straight USB cable can't do, is provide enough "bus" power to use a mouse or even a USB stick directly from the phone. If you want to use a Mouse you will need to get a dock. I got mine directly from wireless.att.com, and it was only $49.00 back in Nov. when I got it. It works VERY well with webtop.
P.S. Motorola is very famous for doing things like this to force you into a dock, or to lock out certain features that everyone really wants to use.
I made my own dock by using a powered usb hub I had sitting around (it was actually the one that came with Rock Band for my Xbox 360). I did have to modify it slightly so that the 1 pin was powered from the 5V (a simple shunt from the 5V inner pin of the power supply solder joint to the solder joint of the 1 pin worked fine--although it might be wise to insert an inline fuse since it also charges your phone while plugged in).
Otherwise, the only other thing needed is coming in the form of your otg adapter that should short the 5 pin (common) with your 4 pin (ID). I did this by cracking open an extra micro usb cable and soldering a wire between the two.
So, my setup was like this:
1. Modified usb cable to short the 4 & 5 pins to let the phone know to go into host
2. Use a female A-female A usb coupler to join the usb cable to the powered hub (I got mine here from Monoprice
3. Get 5V to the 1 pin in the usb hub to provide power to your phone and for whatever is plugged into the hub.
With this, I was easily able to run a usb mouse and a wireless keyboard that had a usb dongle. Paired with a micro hdmi cable to hdmi-dvi adapter, I am able to use my office monitor and the webtop linux. I honestly haven't really used it much yet (if I found it really useful, I probably would have just paid for the dock).
The obvious easy way is to just get the dock. However, I really like being able to do this on my own and since I had this stuff already laying around. Also, the cheap prices from monoprice (I actually made $4 off of the purchase from a PayPal bill-me-later promotion).
So, you should be able to get it to work if you get power to the bus on your usb (but again, it might be safe to pass an appropriate fast-acting fuse, ferrite core, or something to protect from surges). I haven't had issue yet, but I also don't use it often...yet .
It sounds like a bit of yes and a bit of no. The OTG cable I got is microUSB to female full USB, am I going to need to modify this cable as you've described by crossing the 4th and 5th pins?
I'm thinking about ordering this "7 Port USB Squid Hub" since it has the 5v power adapter, do you think it might work?
Just one more question and thanks for all the help but should I not see any response from the phone when I plug in the cable? I read through some of the reviews for cheap cables on Amazon and apparently sometimes they're just useless.

The OTG cable have should work. The OTG cable, to my knowledge, should already have pins 4 & 5 shorted together. I'm not completely certain, but if it's designed as an OTG, it would probably already have that done. If you have an ohmmeter/multimeter, you could try to check (it's hard to isolate the small pins, but you can try). If it's already going to the USB female (type A), you will then be able to directly attach your hub when you get it (without the need of the coupler I had to get).
When I used mine, there was no notification that said "Hey, I'm in USB Host Mode!". However, if you successfully have a mouse attached, you'll see a mouse cursor arrow on your screen.
Have fun with it and if you can't get it to work, let me know and I'll try to explain with even more detail (perhaps with some pretty pictures) of what I did. I more or less went off of what I could glean from reading what others did.
It works great! Also, it is weird to see the mouse on this little a screen, it seems oversized.
I just plugged everything in and it worked off the bat. I'm using just two items from Amazon I got for under 12 bucks (plus, of course, the keyboard and mouse I already had for my computer). I don' think I can post links to the forums yet but the ASINs for the items if people want to do this on the super cheap are as follows:
B0043TBCDS 7 Port USB Squid Hub, a whopping $5.19
B005N55WHI Micro-B USB OTG Cable... $5.99
I chose these because of their Prime eligibility and also for their form factor so as not to cover the HDMI port, I bet it's not impossible to get these even cheaper.
While this isn't technically a replacement for the dock since I had to root the device and I have to press "Load" in Nebtop if I want to go to Webtop I'm extremely pleased with the results.
I also love that all the soft keys are available. The ones I've discovered are that right button on the mouse as well as Esc are Back, the Home key is Home, clicking the wheel as well as Ctrl, Cmd, Alt and a whole slew of others bring up the Menu, but all I can find is F5 for Search.
On another note, while the phone does charge when hooked up, a practical boon, the screen still times out despite having the "Stay awake" feature checked. This is annonying when the phone is on it's side accross the room and I have to squint to see the cursor and swipe it unlocked sideways as well as click back into Mirror Display.
I've heard that the External USB Adapter from ASUS is a notoriously difficult beast to locate. It's marketed to plug into a bare tablet and provide a Host USB connector. But, would it also work in the charging port of the keyboard dock giving a second Host USB port? (Yes, I know a hub would do this. But If one wants this device to connect USB storage to a bare tablet, would it also do double duty and work with the dock?)
It certainly sounds possible. Mostly because I think the internals of the keyboard dock are a hub already basically.
One usb going to the card reader, one going to the usb port, one to the keyboard function, and another as a passthrough to the proprietary data port.
So by using the usb adapter you are just converting the otherwise unused data port into another usb port.
since there both 40 pin connecters i imagine that would work

That is also my assumption, but we all know what assuming does. All depends if all the signals are passed through, and if there are any lag or transmission line issues.
Has anyone tried this to verify if it does or does not work?
I know this is probably more for Microsoft Surface Developer Section but seeing how I am still pretty new I don't have enough post to be able to post in that area.
I am mainly curious if anyone knows the pin outs for the Touch/Type Cover connector on the bottom of the tablet and if it uses standard USB or if it is some kind of special propitiatory type connection that would say connect the keyboard membrane to the keyboard controller that may be in the tablet? If it is just a standard USB connection I am thinking about cannibalizing a touch cover to see if I can create a home Grown Dock so to speak for the tablet that would have a USB hub for keyboard and mouse and a USB to Ethernet adapter that works with the tablet. The USB hub will draw power from a modified Power Cord for the tablet IF I can figure out that electrical later on to where it wont fry my tablet or other accessories but first I need to figure out the first part.
TLDR Does anyone know if the touch/type cover user a standard USB protocol and if so what is the pin layout for the connector on the tablet. If anyone can help that would be appreciated.
I just received a surface and they through in 2 type covers. said, "keep it" on a sticky note. I am now working on figuring out what the connectors are. I dont see the point of having 6 connectors, so I think that some may be ground or false. I will open up one of the keyboards to see what ships they are connecting to. i would think it has to be usb. I know that the 6th pin, that is 6th from the left pin, is 1.8v when grounded. I am guessing that the voltage goes up once the surface detects the attached keyboard. I will write back, let me know if you have figured anything else out. seems like we are hte only people on the internet who even care at this point. and microsoft is literally giving away surface computers.

any progress?
i already build a power wire, with a 5,5mm plug to connect it to my Intocircuit PC26000 for more juice on the go, and for a second charger.
you can see the pinouts of the power plug in the attatched pic.
let me know if you got any results for the cover connector so far - if its USB, i will implement my UMTS stick into a cover
Cheers!
just got pictures of the cover connector, see attatchment.
in fact all the 6 pins are connected. USB 2.0 would take 4 of them.
my guess is that one of them could be a switch, to turn the device & keyboard on and off.
any progress
Curious if anyone has made any progress on decoding the pinout, figuring out if it's usb or not?
i didn't do any further research - but it guess it's usb, or at least kind of... as it shows up as USB device in the device manager...

Judging by the connector and the fact that the covers are USB-based and can be used reversed, the pinout makes perfect sense. The likely possibility for the pinout is as follows:
Power Cover connector (Using pin labels in picture)
1/10 = Power cover +ve
2/9 = Power cover Ground
Touch/Type connector (Using pin labels in picture)
3 = +ve
4 = Ground
5/6 = Data +ve or -ve (reversible internally)
7/8 = Attachment direction detect
Pins on Touch/Type cover itself (Pinout from left [1] to right [6])
1/6 = +ve
2/5 = Ground
3/4 = Data +ve or -ve (reversible internally)
As to if the USB data pairs are swapped on the SP or the Cover, we cannot know without more information. Depending on the voltage supplied or the presence of unauthorised hardware detection (e.g. the ID chip in Apple earphones, I doubt it), custom USB devices should be fairly trivial (electrically).
I know this is an old thread but has anyone made any further progress on this? If not, I'm considering experimenting myself with a spare touch cover and a raspberry pi

Nope, im sorry, i didn't make further progress on this, exept what i already posted.. it is a USB connection, you can easily verify that yourself by looking at the Touch/type-cover in the device-manager...
I guess you can easily connect other USB devices if you build yourself an adapter..
but there could also be some kind of verification, if so then its most likely software based, if you hit a barrier, try reverseing the type-cover driver, you might find something there...
One additional info: the big outer nipples can be used to charge the device.
Peace
If I were to leverage the bottom grooves for charging, can you tell me which pin is which? +/-

Hi tfBullet,
When you say "the big outer nipples can be used to charge the devices" are you referring to these...
Power Cover connector (Using pin labels in picture)
1/10 = Power cover +ve
2/9 = Power cover Ground
Any new discovery?
Any new discovery?
will the power output still be live, if the data signals are not shorted? e.g: IOS devices
Can we just connect the keyboard via usb to a windows pc?
I don't think this is true USB, as there is no 5 volts anywhere on the connector, only 3.3 volts.. It may be USB, but needing to be level-shifted before you can use it. It may be potentially a way to get another USB port on the damn thing. Why did they think one USB port is enough? I have been trying to boot it from flash drive, but need keyboard as well, but the USB will not boot with a hub connected. Grrrrr.

i want to connect the keyboard itself to other devices
Hey guys
Good thread going on , i would like to see if any one of you ever thought about to use keyboard itself not the port , for some reasons I would like to use the keyboard on other devices (i mean kinda convert the pins to a USB port and use it on other pcs or what i really desire about is using it on Xbox) i want to see if any of you have any ideas or information about this , i mean is this even possible ? I've read the whole replies and most of them were about the port on surface and yeah its really cool , but i want to see if its possible to do , cause if its possible then it would be a lot easier than the port on the surface
Thanks

Well, take a look at the link Neakmenter posted, the guy there analyzed the communication, turns out it's no standard USB, it's proprietary.. Which means, there is no easy way of using this keyboard anywhere else than the surface... You would need some kind of microcontroller which connects to the keyboard, interprets it's signals, and relays them as Standart HID signals to a USB port..
The connector alone is a problem as well, you'd need to 3D print a connector or something like that, it's just not worth the effort i guess [emoji2371]

Hello All,
I'm a new owner of a Galaxy S6 Edge, coming from a S4.
I had a Samsung multimedia dock for my S4, that had 3 USB ports, a HDMI Out port and a 3.5mm audio Out port. I purchased a wireless keyboard / track pad and plugged it into one of the USB ports on the dock to make typing texts & navigating the phone easier while at my desk.
Unfortunately, the male micro-USB plug on the Samsung multimedia dock does not fit the micro-USB port on my S6, rendering my wireless USB keyboard useless.
I've looked all over the internet and can't seem to find a similar docking station for the S6. Does anyone know of a docking station that has USB ports that will work with my USB wireless dongle & keyboard?
Much appreciated!
Hi,
Thanks for your report. It seems strange to me that the S6 micro USB port is different, should be the same old 11 pin that the Samsung used. Stupid question, but did you try inserting it the other way around, with the phone back facing you?
For your exact problem, with the keyboard, I assume the old USB On The Go adapter will work on S6, same as it does on S4, S3, Note2, etc. It's this one: http://www.samsung.com/us/mobile/cell-phones-accessories/ET-R205UBEGSTA .
There's also a HDMI adapter, http://www.samsung.com/de/consumer/mobile-devices/accessories/connectivity/EE-HN910FWEGWW. Maybe those 2 can be combined, instead of using the dock.

Thanks for the reply!
Way ahead of ya on making sure the micro-USB plug on the docking station is facing the right direction. I tried docking it backwards and the plug n' port absolutely do not fit that way. It's facing the right direction, just that the port on the S6 is not able to accept the plug on the docking station....despite both being Micro-USB. I did notice, however, that the plug on the docking station had two small grooves indented in it, that looked different than any other standard micro-USB cable plug. It could be that those indentions made the device proprietary to the Samsung range of phones that released during the S3 / S4 years (including the Note 2 & 3). If you look at the compatibility of that docking station on Samsung's website, you'll notice that only the S3, S4, Note 2 & Note 3 come up.
I suppose the USB dongle you linked could work, but reading the device laying down flat, while trying to type on the keyboard might be problematic. You'd think that someone would make a universal micro-USB docking station with USB ports...but I haven't been able to find it.
I'm pretty sure the S6 no longer supports MHL which probably explains why the dock doesn't work either.
You can still go USB OTG, which should let you use your keyboard and trackpad mouse devices.

Interesting.....so are you saying that the micro-USB male plug on the Samsung docking station also had MHL connectivity integrated in it, which is why it's form factor is slightly different than a standard micro-USB plug?
The only times I've ever seen a MHL port on mobile devices was as a separate, similar looking, but different port than the micro-USB port.
I supposed all the wireless mirroring tech out now makes including hardware mirroring functionality not needed.

That's correct, it has to since it offers an HDMI out on the dock.
http://www.thegadgetqueen.com.au/wp-content/uploads/2014/08/5-pin-vs-11-pin.jpg
You're also probably right in your assumption that MHL isn't really needed anymore due to the widespread wireless screen mirroring technologies.
