[Q] Loose MicroUSB Port

My MicroUSB port feels loose when I plug in a cable, is there anybody else that has the same issue or is it just mine.

Mine is also a little loose, although it's not the physical microUSB port that's loose, just that the plug wobbles in the jack.

Yeah thats what I meant. I think motorola might have made the port shorter so it takes up less space but sticks out. My otg adapter always wiggles around a LOT. And it disconnects if I don't hold it in a certain direction

loose micro usb

after 4 months of use I'm already getting a loose micro usb port... time to break out the needle nose pliers
anyone else got a loose port ?
also same thing on my wd passport, they need to make these connectors a little better like a socket for a wrech

And how do you make it tight again?

You don't. It means you have broken micro solder joints and it is only a matter of time before the port fails completely.

Well that sucks

the actual female connector isn't loose... what the deal is when I put the micro usb in my phone it just falls out easy after I plug it in and then go to move the phone around...
what i had to to was crimp the female part on the phone just a tiny bit so that the usb sticks without falling out
same for my portable pass port ... I gues after awhile of stciking and pulling it gets loose

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.

I'm trying to not have cables running everywhere like I currently do. I've already got an aftermarket XM radio next to my radio which uses up a cigarette light adapter already.

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.

Tf300t keyboard dock mod USB connection

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?

Loose micro USB port

As times goes by your micro USB will be more and more loose to fit your Android. It will not click on the connector and the charging of the battery will not start.
This is the thing to do:
Apply a sligth pressure on the sides of the male micro USB connector, that will compress the micro USB from side to side, and it will fit your Android again.
You can do this with a set of pliers or a vise.
If you go to far just press from top to bottom until it fits.
