I have just bought an imate 9502 with a broken charger port (usb plug) inside someone has tried to fix it by linking the pins from the usb port to the pcb but have failed so bad that they have completely f*ct where the pins soilder to the pcb, i was hoping someone with a 9502 would be willing enough to open theres and take some macro photos of the usb port so that i can attempt to trace back where the tracks go and fix my phone.
Any help would be great thx.
P.s in the meantime does aybody know where i can get an external battery charger?
I ended up fixing it by removing the old usb plug and replacing it with a new one and than tracing back the power wires on the pcb than i bit of trial nd error but in the end found them, soildered some tiny copper wires back to the new plug and it now charges perfect
Only downside is that the usb still doesen't work so no sync with the pc at all
which usb plug did you need and where did you get it from?
it would help alot as i am also thinking of doing this to mine
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.

Why not booting on a flash drive and use the usb for keyboard???
There's someone here who's made some progress...

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]

Hi guys.
Earlier this morning. My HTC is not charging. I've check the micro-usb port and it appears that there is a problem in the port because there is a brocken pin. I've tried to re-align it and out of luck, the pin broke. I am wondering if it is difficult to replace the micro USB battery port of the HTC sensation. I saw a post on incredible S section and it's easy to replace it as the USB port is just connected on the board via ribbon. Have anyone have encountered the same issue. Worse case scenario is I will need to have the usb port be remove on the phone and replace by a new one, but I am not good on soldering stuff and I might mess the phone big time. I hope someone can reply thanks.

At ifixit you can see a picture, that shows, that the port is soldered to the board.
I think it will be hard to solder a new one to it, since the pins are very tiny. Maybe you can find a replacement board on ebay?
Hey guys,
I dont know if Im right here, but do you have an idea about replacing the micro usb port on a tablet? I have an old archoos 80 g9, but its not usable anymore because the pins inside the micro usb port are bent. I tried to fix it but no luck yet. I thought maybe replace the complete port on the tablet.
Did anyone do something like that before?
Many thanks for your help.
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?
