Tf300t keyboard dock mod USB connection - Transformer TF300T Q&A, Help & Troubleshooting

Hi all,
I am trying to mod my old tf300t and keyboard dock into a dex dock for my note 9. Im not worried about the tablet portion as i can get a lcd controller for the panel. However ive been soldering and desoldering for the last 3 days. I am trying to leverage the docks kb controller and add a usb connection or modify the dock port into a usb.
I have looked at the various pinouts but cannot get the keyboard working.
I dont care about audio or sd card or the extra usb port.
Any help or pointers would be great.
Here is a mockup of the pinouts i have soldered based on the pinouts i found
Ive been trying to test it on an old s7edge incase i wire something wrong. It detects a regular keyboard but when i try this nothing...if i use the wall charger i see that the dock is charging but still nothing at the dock connector. Ive been trying with a usb 2.0 cable. Connected to the d+ d- vcc ( all 3) and multiple grounds and i pinned the sense pin to ground as well.
I have also tried to open the charge cable and solder the usb to the data pins on that both with and without ground. And use a 5v plug and the original asus plug.
The dock port is basically garbage at this point so if i plan to use that i need to use the 2 20 wire connectors and map the individual wires .

I have managed to get the s7edge to detect that something is connected. However i then resoldered the pins to try more as it wasnt working. So i need to go back to the beginning to try again. I believe my issue was due to the otg aspect of the usb. Im using an adapter for the phone but i also tried to wire the connector the same way. Ill take some pictures of it later if i can get it working

So not sure if anyone is following this thread but i have made progress.
I have totally butchered the original 40 pin connector and now am tapping into the 40 individual wires that connect the main board to the connector pcb. I can get my s7edge to detect that the usb connector is attached but it keeps telling me that a high power usb device is attached and that it needs an external power source.... so today i busted out the multimeter and i believe i connected one of the usb host vcc connections to the other vcc connections so i separated this. I also believe that the s7edge has some usbotg voltage issues so im going to test it with an old macbook pro with windows to see what it picks it up as. When i get some more time i will try to trace the other wires there might be something else needed

Maybe
Nice job, I'm not particularly knowlegdable in electronics but I remember there is a battery portion in the dock? Maybe it causes some error during otg?

[Q] micro usb cable help (pinout++)

I bought some really cheap retractable cables of ebay. When I got them they didn't work at all. I opened and rewired the micro-usb connector - the cables were connected all wrong, but after a little soldering I think they're correct.
Now the cables are working fine with my Nokia N82, but when I connect them to my Desire and Desire HD my computer won't recognize it as USB devices, only charging.
I've looked at the pinout here http://www.kineteka.com/microusb-b.aspx - should pin 4 be connected to GND to use it with HTC?
Any tips?
I was curious of the pinout, thanks for the link.
As far as wether the pin should be grounded, well... if it's not working ATM ground it and see if it works? Since you're successfully charging the phone you know you connected the +5 correctly, grounding any other pins won't cause damage...
Cheers
P.S. Also sometimes good to check the obvious, did you enable the Mass-Storage option in Android?
I've had similar issues with USB 1.1 ports.
Are you connecting it to a USB 2 port??

[Q] USB host mode, specifically via Nebtop

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.

Hardwiring microUSB into a Car

I'm looking to mount my phone to the "A" pillar in my car, but I don't want cords running all over the place. I'm looking at doing an install similar to what people do with radar detectors by hooking into the fuse box inside the car (with an adapter like the one found here). This would be just for power. I understand how to wire it up theoretically (don't need to hook up the data wires, just the power and ground). I'm just looking for a mentor to make sure I do it right.
Has anyone ever done something like this using an adapter like the one I've mentioned? And what size fuse did you use for the install so you don't hurt the phone?
On a side note, I'm driving a 2006 VW Jetta, if that helps in any way.

When I bought my car it had some hard wired cable like that, plugged an old phone in to be safe and it didn't charge properly. I scrapped the idea and just got a car deck with double usb and ran the usb to my arm console.

What exactly do you need help with? - There are 4 wires in the usb cord. Use red for positive wire but DO NOT connect directly to 12v. USB is 5v so connecting to anything higher WILL fry your phone. You will need to get something that converts 12VDC to 5VDC. Red wire is 5v positive and black is your negative (ground). If you wanna do it cheap and easy, go buy a usb cigarette adapter, take it apart, then take the wires going to the metal connectors and connect them to your power and ground. then just plug in your usb cord and hide the whole thing in the dash.
Hope this helps.

Yeah, I started looking into it and realized that 5V /= 12V. I'm currently looking at using an old cigarette lighter adapters internals and wiring them into one of those fuse adapters (it'll convert the 12V down to 5V), then take the wires and hook them into a USB cable. I've got to do some measurements and all, so I'll respond back with some pictures of when I start the project. Should cost less than $20 and about an hour of time.
Website showing detail
Alright, I have finally done the project (just have to hook it up). This website shows all of the details. I did use an add-a-fuse instead, but it is essentially the same idea. I will be adding it into my car later today.

[Q] MS Surface Cover Connector Pinout

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]

[Q] Philips AS111 force to charge

Hi all,
I have a Philips AS111 docking station/bluetooth speaker/charger. Worked perfectly for my SGS2, however, since I bought a new phone (Sony Xperia Z1 Compact) I'm experiencing some problems.
I bought an micro usb to magnetic connector adapter to be able to connect my phone to the dock without having to open the flaps all the time. I took it apart and it basicly splits the first and fifth pin of the micro USB connector to the pins in the magnetic connector. Unfortunately I may not link to external images...
Unfortunately, my phone does not charge when using the adapter in combination with the Philips dock. It does when using the original Sony USB charger and the adapter, so the adapter is fine.
I measured the voltage on the two pins, and it's 0V. I even tried to fool the dock by putting a 1.5kOhm resistor over several lines. Only when I put a 1.5kOhm resistor between 5V and the connector housing, the dock responded by turning on Bluetooth. Voltage went crazy, flipping between 0 and 3V, but phone still doesn't charge.
I think the sollution is to fool the dock by putting a certain resistor between certain lines or by shorting certain lines. Does anyone have a clue how to fool the dock to think there is a device connected, so it opens the +5V line?
Thank you very much!
Nobody into usb connection protocols? :crying:
Finally got it working. Eventually I needed to connect two wires together inside the device. One of them being 'CLAS1' and the other was Ground. Both could be found on the connector going to the micro usb plug of the device. Unfortunately I can not post a link to the photo I made of it.

Hello!
I've just bought an AS111. Charges perfectly my SGS4 but it doesn't do a thing when I try connecting my SGN3 (the one with the micro-usb 3 connector) to the Philips dock. I know that the micro-usb 3 is backwards compatible but I do believe that the AS111's dock outputs too little power - or something like that, I am no expert.
I was wondering that maybe your experience could be of help to me. What do you think? If so, could you please guide me through the stuff you did to the dock? Thank you!
