Windows won't recognize t989

Hello all!
First: I promise I searched the forums and google as hard as I could!
I'm running AOKP JB with CWM, although the problem was present on stock ICS from T-Mobile.
Symptoms: Computer and phone will refuse to acknowledge any connection (nothing shows up in Device Manager), except the phone will still charge. If I do the "remove the battery with USB plugged in" trick, the first time I do it, it will recognize an unknown device, but kies and adb won't recognize it. If I unplug it and plug it back in, it'll go back to not acknowledging any connection.
I previously programmed it (when I was still running stock ROM) via ADB via WiFi, but I need to be able to use ADB via USB. Besides, I can't seem to get ADB over WiFi anymore.
When I plug it into a different computer (Win7), it will, however, recognize my phone.
Earlier this year, before I ever tried programming via WiFi, it connected to my Win8 machine with no problem. I don't think it's a problem with the wifi setup though because the ROM was reinstalled and of course I've restarted ADB in USB mode in the months since...
What I've tried:
Reinstalling Kies
Reinstalling Samsung USB drivers
[^]Restarting the ADB server
Updating ADB
Trying different USB cables
Trying different USB ports
Toggling USB debugging
Toggling MTP mode
The UART thing from the dialer
Restarting the phone and the computer (of course)
Checking to see if my computer's USB drivers need to be updated
The android terminal command "setprop persist.sys.usb.config mass_storage,adb"
Pulling and replacing the battery while connected via USB
Crying in a corner
If anyone can help me, it'd be greatly appreciated! I'm all out of ideas and Google is no longer helpful =/

try to uninstall the drivers that are present anything samsung related to your drivers ... then connect the phone and let the process do its thing if you have the samsung drivers saved on your PC and the drivers still aint working update the drivers and then manually click where the drivers are to install them and hopefully it will work and when you tried MTP is it the only option it gives you no storage or anything ??... and is usb debugging on when you are trying all this ??

I tried on my work computer that didn't have any samsung drivers and when the "unknown device" dialog popped up it didn't do anything or install anything, nor did it show up in Device Manager. Unplugging and replugging it back in did not reproduce the dialog box. Togged USB Debugging and still no dialog box saying it recognized it.
The thing with the samsung drivers is that they're self installing so even if it popped up in Device Manager, I wouldn't be able to manually update the drivers =/
I tried MTP both with and without USB Debugging, although it also gives the option for PTP.
At this point do you think I should unroot and go back to stock? It's not been recognized on three computers now! =[

Are you using the stock cable? My computer wouldn't recognize mine without it.

Both the stock cable and a generic cable.

Similar problem
Similar problem as the OP. And hi guys, it's nice to be on these forums.
My device, when I plug it in using the stock cable, doesn't even charge. It doesn't show up in device manager, nor does it give me a notification, or say it's unsupported and bear that yellow icon. I have tried using different USB ports, I have tried the toggling USB debugging, I have tried restarting phone, computer, and taking out battery. I have tried that PDA/MODEM dialer trick. I am using 4.1.2 Jellybean, not rooted. (that WAS my goal,, until I hit this roadblock) I have not connected it to the computer in the past, it's relatively new. I'm thinking the cable is bust.
Any suggestions would be appreciated. It charges fine through a wall outlet plug, be it generic or stock.

so guys ive come to a conclusion i think its something in the samsung usb cables try getting yourself a blackberry usb cable , TRUST ME !!! ever since i got my phoness etc... tablet and yadi yadi samsung usb cables have always seemed to give me problems i think its because they are multi data/charging cables and when using the blackberry usb cable i have never ever once encountered a problem with any of my phones sd/storage problems do yourself a favor and pick up one of those cables and you will be golden !! if not then i guess im the only lucky one :LOL here you go http://www.amazon.com/Blackberry-Travel-Adapter-Micro-Cable/dp/B004VMVSYK/ref=pd_sim_cps_2 5 bucks!
Edit also one more test boot into recovery and click in the advanced menu and see if mount usb works for you in recovery mode ??

FIX (try using a generic cable)
I actually solved it on my own! After borrowing a generic cable from a friend it booted up! The Samsung cable was just not doing its thing.

yeah im telling you those cables they provide are JUNK!!! i only use my samsung to charge because they do that well but data they are str8 CRAP!! glad you got it up and going

OP
Hope OP will have the same luck as me...pray to the Android gods...

[Q] USB Problems

Hey guys,
Now, my Galaxy Note 2 was rooted. When I connected it with the USB cable to my PC the PC didn't recognize it (it used too, but then suddenly it stopped connecting). It still charges but no new device is detected. No Kies, no MTP, no Odin.
I didn't worry too much, because being rooted I could still do everything using the external sd card.
However then the ROM for Android 4.3 was leaked I stupidly installed the stock version. So, no root, and no capability to mess around with the phone.. I also have no viewable option in Settings to set the device connection to MTP, or PTP mode as usual, but maybe that's because of Android 4.3
I have bought a new USB flex part, opened it and replaced it but it still didn't work.
I download a version of phoneutils.apk and installed (because the one on Android 4.3 didn't have Qualcomm USB settings option) and choose the correct options, but still nothing.
Do you have any idea what may have gone wrong? Or what I can try to do?
I desperately want to root the thing.
Thank you very much! I appreciate any suggestion and reply.

Hi!
This might sound stupid but... have you tried a different USB cable? Or USB port? Sometimes this can solve these kind of issues. Take a look in your computer's Device Manager and see if you have any problems with the USB hub driver. Also try to connect using a different PC and see if that works.
You can try and boot in Download mode (Vol down + Home + Power) and see if ODIN sees the phone. If so, you can flash another stock firmware and see if your USB works then.

Yea tried all that! No success. /:
Phone goes into download mode but Odin does not recognize it..

Problem: conecting A5 to Laptop

Hi, I am needing some help. I connect my A5 to my laptop but a pop up from Win10 says that doesn't recognize the usb device. And continue saying that the last usb device connected didn't work correctly and windows didn't recognize it.
I think this happened after installing ADB and some other things like ZX3 to try to unlock my A5 and then uninstalled them, so perhaps I deleted some drivers in the process.
Can you suggest any solution for me to try?
Thanks in advance!!!!

Try connecting your device and then deleting its drivers in the device manager. After that reconnect it and it should show up as normal. Let me know if it helped

No, already tried that. Same message. Thanks!

I tried another usb port on my laptop, and recognize the phone. I don´t know we after some cel phone configurations I lost connection and recognition.
I tried again the first port and touch some items in the developers option, set the MTP protocol and now it seems working.
I stil don´t understand what I have to do to establish a good connection for every time I need it.
Regards.

Hi all. I'm back because I stll have the same problem. Can't connect A5 to laptop. The message says that there is a bad descriptor. It is the 43 error code from window 10. I tried downloading lastest Samsung drivers that comes in an .exe file and installed them. But same error.
Even trying to update the error driver to the lastest samsung usb driver, window says it already has the latest drivers and do not installed them.
Every suggestion from searching in google tried. Don't know what else can I do!!!!
Thanks for your suggestions!!!!!

Try to turn on usb debugging in developer option

Already on.
SOLUTION!!!!!
I was using an old usb type-A cable with a usb type-a to type-c adapter. I tried using the original Samsung cable and it worked!!!!
I can believe this was the problem!!!
Hope I can help another with this! Thanks to all for your support!!!

Hi, I continue finding problems to connect A5 with Laptop. After finding the original problem was the cable, I now use always the original cable.
The problem is that the phone doesn't appear in windows explorer unless I go to developer options and set the USB configuration from RNDIS (Ethernet USB) to MTP (Media Transfer Protocol). After that, a pop-up appears asking for permission for data access. I have to agree with the pop up to see the phone in the laptop.
I think I have to change permissions to granted for ever the MTP. Am I right? Where do I have to set it?
Thanks in advance!!!!

New update!! I have just chat with Samsung. The told me to dial *#0808#. That access the USBSettings options. There I changed the default to MTP + ADB.
Now I no longer need to access the development options. It still appears the pop up, asking for permission, but for now I can live with that!!!

Your problem seems simular to what I had.
If you are sure the software settings are ok and that doesnt work, remove the backcover remove the battery connector, put it back again and see if that works. Does charging work?

Thats weird my s2 tablet has USb problems to. It stopped reading OTG usb connections and the PC. However it is always able to charge. I have noticed that when it does finally read on the PC it seems like the drives dont switch right and my battery wont charge. It got to the point I dont even try to plug it into a pc or USB otg just incase it quits charging I have SD card and twrp for installs so I use that instead. Most be a problem with the usb port and drivers.

I dont know the answer nor the solution.
What I noticed however is that I used my tablet as an monitor for an USB web cam.
The problem (charging but not being able to connect to PC) started AFTER I removed the webcam.
The app I use (USB Camera Pro) has an option "remove camera safely"
If I use that option everything works fine but if I remove the cam cable without pressing this option I cant connect to my PC anymore and have to unplug the battery.

I am having a similar issue and would be grateful for help. My Tab T815 has a clean install of the latest Android 10 Rom and Pico Gapps via TWRP 3.4. All seem to be working great apart from the USB OTG. Specifically, I am trying to connect my DJI Mini drone controller and it's not registering it plugged in. I also have Android 10 on a galaxy S5 and have no issues at all when I connect the DJI controller to the phone. I have run a diagnostic app that says OTG is compatible with the T815 so am now at a loss on what to try next. Could this be an issue with the Rom?

Problems with USB connection

Hello! I have a mi A2 lite, I can't connect it to the computer using USB, it doesn't install drivers, it doesn't appear on installed devices. I've tried all the tutorials available on YouTube, but it doesn't work, does anyone know what I could do to fix this?
- I already downloaded the drivers and installed manually, but nothing changes.
- I've tried on multiple computers and none work
- When I bought the cell phone it connected, but after a while no more.
Does anyone know any solution to this problem?
Thanks!

Did you allow the phone to talk to USB. You must use the notification to enable file transfer or set the default in settings or enable debugging if you want it to show up to USB.

It does not appear the notification, but I have already tried to activate by the settings too, I already connected the debugging mode, but it also did not work. When connector it only loads, there is no other action.

I'll take it to a technician to check it out, thank you very much.

I have the same prblm ...... any solutions? Help me please

Same here on v11.0.12. Its a driver issue. You need to install latest xiaomi drivers + qualcomm drivers. I fixed it before but it doesnt work again after i uninstall drivers.

I connected phone to PC with only old original short cable, no other cables worked :/

Have you tried to clean phone's USB socked? There are some spray contact cleaners, that can be used for this purpose.
