Hardware Question - USB connector - Kindle Fire Q&A, Help & Troubleshooting

Does anyone happen happen to know, specificly (ie. manufacturer, or distributor part number or model number) what USB connector the KF uses?
I just bought a used KF and the connector is failing. I have someone that can attach a new one for me but I haven't been able to figure out what connector to buy. Lots of searching and looking at pictures but i haven't been able identify it for certain. If I have to, I will pull the board and look at it but I thought I would ask first.
Thanks

I probably cant help you much but I use 2 different ones both non stock. one is for my droidx seems a little loose but it functions. The other is made by belkin standard usb to micro for media transfer this one is a little tight. when you say fail can you clarify that?

Thanks for your help. I am looking for the connector that is soldered to the motherboard inside the KF not a cable. When I plug a cable in the connection is very loose and I have to wiggle the cable a lot to make a connection and if I let go of the cable the connection fails. I have tried several cables, as well as, the wall charger, all with the same results so I am sure it is the connector on the motherboard. The cables work fine on my other devices.
Thanks again for your help.

its sound more like a loose fitting cable than the connection point itself I wouldnt know how to go about replacing the device end. Possibly might require a new motherboard to do so unless your pretty crafty. Wish I could be more help to you.
The belkin brand is much tighter fit I purchased it at target 16$

micro female/male hdmi and usb for Lapdock

I bought these on ebay. The HDMI is short but worked but when I connect both cables to lapdock, the USB is not being recognized so the keyboard/mouse is not working. I want this just to act as an extension so I can use full lapdock abilities with cables. Any idea what's going on (cable charges on plug but does not charge on lapdock)? Maybe someone has better usb cables.

From your title I've been looking for these (or similar) cables for a long time and have been unsuccessful. However I have yet to try them.

i don't think it will work either way, tried a few things like this with no avail.
why wouldn't they? Cheap build quality that doesn't include the data wires? Hell I'll be willing to splice two cables together to get our desired effect, the only problem is that cords with a female micro usb are incredibly hard to come by
So that is what you think it is? No data on the usb cables.

the only reason that is my suspicion is because there are many "charging" products out there that don't really need data. Why there would be a need for such a small charging extension cable is beyond me, but it's the only solution I can think of, but I have no way of confirming or denying it either. The ebay descriptions seem to imply that the data wires are there, but we all know how reliable ebay can be...
Another idea I had was that it might be sensing the resistance in the cable, since, if I remember correctly, that was how some think/though the car dock puts the atrix into car mode without a magnet as is/was commonly used. Again these are just ideas.
Or the cable is just so poorly made that it's defective...I honestly have no clue
Has anyone got full lapdock capabilities using extension cables? I can only get the screen working and not the mouse and keyboard.
The HDMI extender was the hard one to find. There are other micro USB extenders out there, theoretically with all wires connected....

Kind of makes me wish i hadn't hacked up my lapdock to work with the Otterbox
Where did you get your HDMI extender? I got mine from All4Cellular but it's quite short. Will have to get another HDMI one if the usb cable you recommended works.

The HDMI certainly looks like it may work but the reason I didn't buy that product from ebay a few weeks ago was because it was $50. Now miraculously, it's only $6. Maybe I'll get that if the USB cable I just bought that was suggested works a few posts back.

The HDMI cable seems to work. On the lapdock, with just the HDMI cable hooked up, it functions like it was it's an entertainment center.
The USB cord will need to be modified a little bit. I can't get it to seat right on the USB jack of the dock. I'll need to shave it down a bit as it doesn't sit down snugly.

I ordered the USB cable and experience this same problem, though I am waiting for my hdmi parts to come in (by April 6th I should have all my parts...). The cable itself works flawlessly as a micro usb extension cable when connecting it to the computer.
again as mentioned in the other thread, you want to be careful with the 5v coming out that micro hdmi port. for connecting back to your phone would be no issue, as the phone charges using this voltage, but hooking the lapdocks micro usb up to a host device probably wont appreciate the 5v coming back up the cable, where normally the usb device would be pulling power from said host, not providing it.
one suggestion is to just clip the red wire inside your micro usb cable/adapter.
btw the adapters i use do fit snugly side by side, without modification.
I've been following this thread for a little while now, and I wanted to share something I found.
I was looking at the Motorola Travel Webtop adapter. And I was curious to see whether it could be tweaked to suite our needs. I naively thought/hoped that I could flip the connectors in the device to make a small adapter to connect the Atrix to newer Lapdocks. Unfortunately as you can see in the pictures below (sorry not enough posts to link to the pictures) the two connectors are connected via a PCB not wires or a ribbon cable. Although I still have high hopes that I can de-solder the HDMI and USB connectors, and use a small length of flat ribbon cable to connect them and then re-positions the connectors in the case, to build a micro adapter to use the Atrix on the newer Lapdocks. Should this fail this will at least prevent others from making the same mistake, and solve the mystery of what's really inside the Webtop Travel adapter.
Do any one know if this Micro HDMI Cable would work for Lapdock.

I believe all Cables are standard. Can this used to Atrix 4g with Lapdock?
I have otterbox case for Atrix and don't want to Remove cover everytime to plug in Lapdock.

USB Transfer Cable for KF

Can anyone give me a recommendation for a Data Transfer cable for the kindle fire? I've seen the threads regarding the factory cable, and have noted that as a possibility, but I was wondering if anyone could refer me to a decent cable that will work strictly for data transfer.
I did purchase this cable from newegg, as it was listed as a charge/data transfer cable specifically for Kindle Fire, however, it only provides charging. It does not provide data transfer for KF, windows doesn't even see the device. Interestingly enough, I hooked up my HTC Evo Design 4g to this cable, and data transfer worked immediately. Just doesn't work for the Kindle for whatever reason. Up till now, I've been using my data cable from the HTC Evo and it works with the Kindle, but I think it's causing issues when I set the KF to fastboot for rooting. Not sure if it's due to the cable or not, that's why I want to try a different cable.
Cable I use
I got this cable to charge my phone and data but works fine with my kindle as well.

@Cryplock and tobiasunruh: Do the cables you linked to work for rooting? My problem was that I have a cable from my HTC phone, but I can't get past the initial reboot to fastboot. Not sure if it's the cable or the drivers. I've heard the drivers can be a pain to get to work in fastboot.
I'm using usb cable that came with my SG2 and it works well.
i'm loading with the cable from the Samsung gallaxy SII.
works great.

Sorry for the really late response but yes I used the monoprice cable to root my kindle. I also have no problems mounting the kindle to my computer. Works flawless.
I've been using the same cable that came with a 1st gen kindle I got for my daughter. It does work for rooting also. I can't post links here yet but if you go to amazon and search "kindle fire USB" you will find it. Its white and looks like 1 that would come with an Apple product.
Any micro b to usb a cable will work for the kf. They don't make usb cables specifically different for different devices, it has wires that correspond from one end to the other to transfer power and data. They are all made exactly the same albeit different qualities of manufacturing, and the cables and ends can go bad from metal fatigue. If you are having trouble with data connection it could just be a loose connection in the usb micro b end or more likely the wrong drivers installed on your pc.
Also a "factory cable" is a modified usb cable intended solely to alter boot mode, not for data transfer unless equipped with some sort of switch or expressly described as being capable of such.

I purchased my cable from a Japanese thrift store for 1.50, but i'm sure any thrift store micro usb would work.
you all are waaay overthinking this stuff here.
both my original KF and my KF HD 7" are two of the least pickiest microusb devices I've owned.
The reason some devices (i.e. Samsung) are finicky is becauase they connect a precision resistor to two pins on the micro USB connector and their device checks for the presence of their OEM cable by measuring a the power drop over that resistor. One of the pins on a micro usb-B connector is NC since it's a 5 pin connector and the usb A's are 4 pin, so a device that isn't specifically looking for something special on those pins will never know the difference.
Luckily, Amazon took the more respectable route of not ****ing with stupid unnecessary **** in their designs. USB is a digital signal, so as long as you're not getting excessive voltage drop due to too much overall length without an active repeater and your logic high/low signals are within the fairly generous tolerances the spec provides for, any cable will work.
I tend to buy the $4 ones on amazon and have had great luck with them. If I munch one through poor handling or someone steals it, I just go to the big old box of spares I have and pull a handful more out...
I use the cable that came with my Kodak digital camera and it works for charging, syncing and rooting.
The original cable works fine to me, but speed transfers are slow as hell!
I'll try some of your tips on new cable (the cheapest one, possibly).

Does Replacing the usb connector on t989 require soldering?

I received the phone and everything was great except i couldnt charge or connect to my computer because the phone didnt show that it ws connected at all (The battery icon remained the same), by mistake I found out that if I tilt up the cable, the phone will recognize it and charge as everything was normal. If I look closely and compare this usb port with other mini usb ports from other devices in the house I noticed it was tilted a bit down. So I put a sliver of duct tape and used it as a shim and put it between the male end of the usb port and the phone case itself, well it seems to work but Im afraid that it wont work for long. Anyway, to the meat of the question. I found some usb mini connectors on ebay for the t989 and when I have looked at the teardown I see that its attached to the motherboard as it was just plugged in, but then at the same time I see two solder points on the mobo as well. I don't know a dam thing about soldering other than what a soldered are looks like. Has anybody had any experience in removing the usb connector on this phone? Or just knows by looking at it how it is attached.
Thanks
Well before you do anything...it's micro usb Ports that you want

Microusb cord falls out of port

Hello everyone,
This is my 2nd note II. My first device had a few problems and now this one seems to have a loose charger port. Also, when I connect this device to my tv via microusb, the tv screen flickers (could be an indicator of a faulty micro usb port). Has anyone had the problem of their charger wire falling out of the microusb port? What did you do to fix it? If you sent it to samsung did they return the device in working condition without any dings or scratches?
Thanks im adv

Mine was perfect for the first few weeks, but eventually got a bit loose so I replaced the USB cable which did the trick. Ive heard of other cases where the usb ports became loose, but not to the point of it falling off on its own.
Have you tried other USB cables on your phone?

hey i did try the usb wire that came with my samsung media dock... its a bit more snug, but it came off randomly after a while. my samsung otg usb cable fits great... the thing that concerns me is that sometimes when i connect my device to my media dock (uses the microusb port) which connects my phone to my tv, the screen on the tv flickers. this could be an indication of a faulty microusb port... but heres the confusing thing, ive tried transferring files to and from my computer via microusb and it works fine, so that would be an indication of a working usb port.
from what you have heard or read, was the consensus a problem with the usb port or the wire?
thanks
Yes, the wire was the culprit based on my reading.
Better have your phone checked. Im sure it's well within Samsung's warranty period
Ironically the best cable i use is a blackberry one, excellent secure fit

In a pinch you can rig up a temporary charger using the POGO pins on the right side of the phone. Just wire the corresponding red/black wires from a cut up USB cable to the correct pins (you can find the pinouts online). The trick is getting the wires to stay on the pins - you can try packing tape. I know this is kind of a dirty solution, but it will work in an emergency until you can replace the usb port.

Well, there is no guarantee that it is the USB board - but you can purchase one on ebay for under $10. The part includes a usb jack as well as a ribbon connector that connects the jack to the main board. There is, however, a chance that you have a faulty main board, in which case, replacing the USB port is not going to fix your problem but the only way to really test that is to buy the part and try it out.
