USB does not recognize my phones - MTCD Android Head Units Q&A

I have a MTCD head unit MX (witson) with Android 5.1, my problem is that the USB port cannot recognize my phones, A note 4 with Android 6.0 (eRobot ROM) and a Samsung GT386T no rooted with stock ROM 4.4.2. The USB port works find with a usb stick, I can play music, pictures, etc. but not my phones. Both have the USB debugging enable.
When I plug a phone it is charging but nothing happens, my note 4 after a few minutes pop a windows saying that there is a problem with the connection MTP and that I need to download samsung Sync etc.
What I want to do is to use the mirror link function.
Any of you know something about this issue?
Thanks in advance for your help.

I believe i read that there is a specific app that you have to run on these to do the mirror link...easy connect, maybe? Did your HU come with an instruction booklet? I was looking through mine earlier and it went over in detail how to setup mirroring through that app.

Yes, when I tried to use EasyConnected is when I saw the problem. The app waits for my phone to be connected, It says that it must be turned on USB debugging, but it is on. Then I checked in the File manager and the USB was not enable there, like if nothing is plug it. If I plug a USB memory it works fine.
I will try today to do a factory reset.
Thank you!

You ever get this solved? My easyconnected never stays connected. WiFi and USB both are garbage.
WiFi randomly disconnects.
USB also disconnects asks me to allow USB debugging every couple of minutes. The phone never remembers the headunit, so it constantly asks me again to allow connection. Must be a crap RSA fingerprint coming from the headunit.

Nope, Still does not work for me. Same symptoms as you. I already tried with 3 differents phones, factory reset and different versions of easyconnected.

I seem to have USB connection working now with only one "allow USB Debugging?" popup, only when I first connect.
What I did was turn wifi off on the headunit. I am not sure why it worked, but I just wanted to turn everything not needed off, and see if the headunit would stop disconnecting all the time. So far so good. I can probably live with one annoying popup, instead of one every few minutes.
Of course you have to keep the screen on the phone on, and the battery in the phone will deplete faster than the headunit charges it, but still an improvement. I had a 30 minute drive today, and the USB never disconnected!

paniqueado, try the da_anton ROM. I just installed it and easyconnect finally works as it should. I just plug in my phone to the USB and it fires right up! One prompt if any on the head unit, and NO disconnects whatsoever.

PC Connection

Hey all, I've had my Captivate now for afew days and I'm loving it, but today I ran across an issue that's driving me crazy.
For some reason when I connect it to my PC I'm not longer getting the Mount SD option on the phone and can't look at my files. I've enabled USB debugging and tried it. I've told it to come up as Mass Storage and tried it. I also told it to Ask when connected and it's still not working properly. The drives show up in Windows but cannot be accessed. I also no longer get the USB notification up in the notification bar.
The weird thing is sometimes if I restart the phone and connect it everything is fine, but then if I go to do it again nothing. Anyone have any suggestions?
Biggest misconception here is that its random, it isn't.
Download kies by samsung and update it and you will get the right USB drivers installed automatically.
If you choose not to do that, you'll Vast have to keep trying different ports or restarting.
Its also possible that you may have a faulty wire but this is unlikely.

I've tried it with multiple wires, and when it works it is reliable, but most of the time it's just not showing a USB connection on the phone.
I spent awhile downloading Kies and it's updates and in Mass Storage mode it sees the drives of the phone but doesn't let me use them. I Kies mode it does nothing... This is so confusing...
Go in here download the drivers:
http://forum.xda-developers.com/showthread.php?t=728929
Be aware, they might take up to 15 minutes to install, and no KIE is not included.
Make sure you close all your apps on phone before connecting to PC. Few apps that use the SD will hold the resource and not allow for PC connection.

I downloaded those afew days ago but I will redownload and reinstall again just incase. I think the fact that the USB notification isn't showing up in the bar on the top of the phone is what's confusing me the most. Previously I would see the USB Icon and something would pop up saying I need to mount the drive. I would mount it and there would be no problem. Now I'm not getting that at all and I've tried Mass Storage, USB Debugging, Kies, and Ask.
I've never had a problem connecting my Captivate to my Windows 7 64 bit computer. I didn't install Kies or any drivers either. Not sure what all the fuss is about. I'm suspecting a lot of PEBCAK errors.
I'm starting to think there are some strange power requirements when connecting the phone to USB. Most of my systems have been fine but on one, when I connect the phone to the front USB ports, the USB Wifi adapter on the back simply stops working. While the phone is connected, the computer refuses to recognize the Wifi adapter. A soon as I disconnect the phone it starts working again.
I've seen people on other forums with intermittent issues getting the mass storage connection to work when connected to the front ports on their systems. A lot of times the front ports are connected through a USB hub in the computer case that doesn't deliver full power. If the phone isn't drawing enough power or is shunting power from other devices, this might explain the issues people are having.
Mine is acting up . I used both teh 5.02 drivers from samsung and the one linked here and similar results. In Samsung mode it goes to the Digital Still camera and flakes and on mass storage it shows two new drives..neither of which is writable or readable. This is on a cap with no SD card and XP sp3. I tried different ports but with the same result.
I was fighting with this all day. I installed, uninstalled, reinstalled all the drivers and kies, but, I was trying to connect via media player and nothing was happening. Then I noticed that there was a small message popping up on the Captivate's screen that said something about the device had to be on the idle screen before it would connect and fun the sync software. Tried turning off all running programs and still nothing. Then, I remembered that I had switched to Launcher Pro. I switched back to touch wiz, and lo and behold, it connected right up and allowed me to sync items with media player.
Interesting. I've been using ADW.Launcher and haven't see this problem except when I don't get the cable securely inserted into the Captivate. I even use a Nokia cable most of the time. The Kies Drivers are clearly the most stable. I downloaded the Drivers from the Captivate microsite and found they didn't support KIES, so I just reinstalled the KIES driver for MTP. Everything else works fine on W7x64.
++++UPDATE+++++ Validating MSHampton post
Well this sucks. On my Captivate, unless you are using TW.Launcher and in the idle screen, the Captivate won't launch MTP so you can connect to KIES. The USB Storage mode works with other Launchers (ADW and LaunchPro), but not KIES or Media. I didn't try PC Internet tethering. I switched between the two several times, and KIES only works with TW.Launcher on my device.
Is there anyone who knows of a Launcher OTHER than TW.Launcher that will interface with KIES so that the Captivate can connect? Or can ADW or LauncherPro be "tweaked" for the Captivate? I was just starting to like ADW.Launcher.

Holy crap, I have that EXACT same problem. I thought it was just the fact that my USB Wifi adapter is a piece if crap (which it is).
Just for reference, what kind is yours? Mine is a Belkin Wireless G F5D7050.

It's the Tenda 311U which is also a cheap piece of crap ($15 at Micro Center.) It doesn't look like they use the same chipset.
I've had the same issue as well. Hooking up the Captivate to the front USB ports disables my USB mouse (on the back). I'm not sure what it could be doing that would lock up the USB bus...
Using Windows 7 netbook
I finally got tired of it deciding and put in the mode to ask me when I connect. the problem i am having is when you just charge it, it does not know that it is just charging and wants to go to ysb mass storage or the other screen. also I use double twist to connect to the phone.
thanks
Jon
The best bet here is to use USB ports on the back of the computer.

If you're still having problems, select mass storage and connect the usb (or select ask every time and it will ask when you plug it in). To access the drive like a removable drive, you have to swipe the icon in the top right of the screen and select the usb selection. Then click mount and it should work! I had a hard time with this too and thought it wasn't very intuitive. Good luck!

Yep, strangely enough using the back ports worked. I'll have to see if a powered USB hub will work and then I guess we can conclude that it's a power issue.

I've set it to both Mass Storage and Ask every time and the problem I get is that I only get the USB icon up top sometimes, it's very rare. I've tried this on multiple ports and multiple PCs with the drivers downloaded and sometimes the notification shows up and I can select mount, but most of the time nothing is in my notification bar at all.
I love this phone but I don't understand why it's so frustrating just to connect it to a PC. I've also tried the Kies methods and it sees the phone, but doesn't let me access the files.

This just solved my kies and windows 7-64bit issue. This should be sticked advice or added to the wiki.
USB Setting no PC- Connection
I just got my AT&T captivate and I notice that under application,usb setting I don't have the PC-internet option in there. This is only what I have under USB setting:
Kies(Firmware update)
Media Player
Mass storage
Ask on connection
So, question is, how do I enable the pc-internet option? Any suggestion I really appreciate.

[Q] USB Mass Storage Won't Connect

I upgraded to Sky-ICS RC7.4 Speed yesterday and today. Obviously the USB mass storage was working earlier because I got the .zip file for the upgrade on the phone. Well, just a little while ago I tried to connect so I could pull those zip files off just to save some room and it won't connect.
I can charge the phone, the laptop(Windows 7) and the phone both make sound/vibrate when connected. BUT, with I go to "Connect storage to PC" it tells me to unplug the cable, which it hasn't before but I did it anyway. I unplug the cable press the connect button again it states to connect the cable, I do. Press the button to connect and I get the same result. I've tried enable USB debugging and try again and it states to disable, blah blah blah.
It's great that I can charge the phone via USB all day long but really sucky that I can't access any of my files via my laptop.
Anyone had this issue or know of any fixes that may alleviate this issue? I sure would appreciate your help.
FYI, USB drivers are installed on the laptop and reapplied after the the issue of not being able to connect USB mass storage...
update: I am able to see the two mounts in computer management on my Windows 7 machine but not able to access them through My Computer.
I was reading from other threads about a possible Windows issue, how I find it unlikely, but I did a system restore from an earlier date and that made no difference. It's still a matter of the phone connecting completely to the pc.
Also tried different ports and usb cables, no avail.
I could really use some input so that if need be I can access the files on the phone to either flash back to stock or at least modify the files I have on there now to let me be able to attach my mass storage. I'm liking the the rom it's just a few little things like this that are making me completely love it.
i have the same issue if i plug in to the front usb ports. no problems with the back and its only been since i updated to seans latest speed stripped ICS rom
I was having the same issues. I turned the phone off, took the battery out, and then restarted it. It worked.

Correct; you need to reboot your phone because you probably connected / disconnected too fast and the phone is bugged out now.
I'm on 7.4 speed stripped and its working fine for me. Did you try installing the Samsung USB drivers exe in the dev forum?

Infuse USB Connection Issue

Recently we have been getting in stock i997's that are having USB issues connecting to the computer. As always we enable USB debugger and connect to the computer however now the units are going into charge mode a few seconds after connecting to the computer and shutting the device down. Once we disconnect the device from the computer it automatically restarts.
Here is what we have done so far with no luck:
-Enable USB debugging
-Disable USB debugging & enable mass storage
-*#7284# was set to USB=PDA, changed to Modem & back to PDA
-*#9090# Didn't see any relevant options
-Slightly bending the USB port
I don't think it is a hardware issue but a software issue that needs to be configured. Any help would be very much appreciated!!
USB
Get it as stock as you can with software. If the USB still does not connect correctly then it is a hardware issue. There was never a problem in any stock rom with USB connectivity.
Just my thoughts. It may not be the phone but the connection-- Computer, cable, oops,-- or drivers.
I'm facing the same problem !
I too have the same problem very weird tried several time stock have no issue in connection. this issue occur after few days not immediately and no regular pattern so can't say what's going on. right now my phone while put on charge shows charging but when un plug it still have 1% as charge no battery put to charge message shows up, tried with charger, usb to computer.
I also noticed before that charging stops and only come in effect when you pull the battery and plug the cable put the battery it will start the phone automatically and charge start up.
Can't ever put in charge in switch off mode as every time it automatically switch on my phone.
I tried several time these step 1. Go back to stock by heimdall , 2. heimdall kernal flash for red cwm, 3 wipe, format, fix permission 4. flash
couple of days work smoothly then problem reoccurs
Did you try mtp mode like with media player mode

Thanks RDomke for the reply.
We already flashed UCKD5 with no luck. Would there be anything else we could do? I agree that it may be hardware if stock doesn't work but we have been getting in too many units out of box with this issue. Not saying that it isn't possible to be hardware, just seems like it's something that could be software related.
SOLVED

RDomke,
Many thanks as we have solved the issue with your advise. The 1st unit we were testing did in fact have a bad usb port. Once properly diagnosed we tested another by flashing it back to stock and then performing a factory reset. Once done issue was solved and worked on many other with same issue.

USB Problems

My computer for some reason reminded itself of not recognizing my Idol 3 5'5 6045k. Two days ago it was all fine and now everytime i connect it to the computer it only charges. I've tried everything from changing usb cables to unistalling andthen installing the device drivers, enabling debugging, restaring either smartphone and computer. Everything I can think of. Please help me out, I'm trying to root the smartphone and without it recognizing I can't do anything, not even transfer files. :crying:

Obvious Question #1: Did you check the phone notification dropdown area to verify the phone is in MTP or PTP mode so it will show up on the pc? As for transfering files...you do have the option of loading up a microsd card with whatever files or installing a wifi adb app to connect wirelessly. You could even use an app like airdroid to let you do all sorts of things.

Therre's no notification after connecting the usb, it just charges the phone, seriously, I've tried everything to enable MTP but nothing does the job. And what do you mean by using an adb app? Can I root my smartphone by a wireless connection?

You are overcomplicating things. 1st...there is ALWAYS a notification in the dropdown that says what mode the phone is in....mtp, ptp, charge only or "cdrom mode" which installs the usb drivers. Pressing on that notification allows you to change the mode the device is in.
As for rooting....all you need to do that is to flash or boot TWRP (details on booting it are in the system image thread) and then flash the supersu zip from inside twrp to your device...reboot and done...but I think in the newer TWRP's they even offer options to root automatically...ie the zip is already built in. After rebooting to your phone you install the supersu apk from google play so you can configure what apps have superuser access.

Your telling me when the phone is plugged into the pc you don't see the notifications below or some version of them at all? If so then you need to fully uninstall the devices in device manager including remove the drivers...then use the drivers in the system image thread (since you obviously can't use the ones from "cd rom mode" which would be the best solution). USB debugging isn't even an issue yet...your phone should still show up to the pc as a camera device (ptp) under just about ANY scenario using even built in windows drivers.

Have you tried a different cable? Perhaps that one is damaged or is only setup for charging? Only thing I can think of.
And then I realize you mentioned that Not sure what else would prevent it from giving you those options.
I'm also facing similar issue after the 2 update. Were you able to fix this?

Which kind of USB cable(s) have you tried specifically? Were they cheap eBay/generic kinds or well known branded ones?
Something as little as a Micro USB cable can cure a lot of problems. It needs to be a well built one by a known manufacturer to avoid problems.

Actually I've been having pretty good luck with the $1 ones from Dollar Tree but the key is certainly to try multiple cables....on some the microusb plug will make it difficult to get a solid connection especially if you have a case on the phone.
You may be missing the point of "trying" different cables. It's not so much the "quality" of the cable, it's the fact that some cables are for "power only", and "will not" transfer data, regardless of how hard you try.
You need to be using a "proven" data/power cable, otherwise your beating your head against the table for nothing.
Just to add, I put a piece of red tape on all my usb cables that are power only, no guess work.

I had the same problem as well. It only showed charging when I plugged in the USB cable. Tried switching cables, turning off and on USB debugging but nothing worked. I finally just rebooted the phone and then it worked again. Strange that it suddenly stopped.
I have a different issue; the different USB modes work fine but I don't have the 'cdrom' option in the USB mode dialog. I've tried various Alcatel ADB drivers that I have found and none are working, using Win7 64. My Idol 3 4.7 is 6039I (US).
Answered my own question, simply install the Mobile Upgrade Q software.
nope, doesn't show up. it's a bug. i had it before, googled until i found a fix and got it working, now it's back to not being recognized. nothing shows on drop down menu.

- Android Auto
- Car
So my question is: Does someone already has a working Android Auto connection with a car´s radio with this phone?
If so, I will continue this in Android Auto section.
Today I upgraded build to: MHA-L29C432B138
Car/Radio: Opel Astra K (MY2017)/ Intellilink R4.0
The connection could be established. But screen of car stays black. When touching screen or saying "OK Google" it accepts voice command.
My Mate 7 works perfectly...
Best regards,
Robert
no idea... working oke on my golf 7 2015 mib2 unit..
u using original cable... i also try ith lumia 950 cable, also usb-c but random disconnecting with this cable.
P9 is also working. I guess the problem is Mate 9.
Mine works with Pioneer but doesn't work well. It Will not play anything already downloaded to the device unless you connect phone to head unit forest and actually play something through Bluetooth first and THEN connect it. All permissions are set correctly etc. And what is with having to give it permission to use the data on the phone EVERY SINGLE TIME?
US model working flawlessly with 2016 VW Golf R... I did have to reinstall audible and spotify after connecting the first time in order for them to show up in the menu, but other than that, no issues with connecting, audio skips, etc. Very happy! Samsung S7 Edge was unusable with AA.
Got the International Mate 9 Pro and AA is working perfectly fine with my Pioneer 4100nex. I'm on the latest Pioneer firmware 1.09 if that helps anyone.
Works like a charm
What settings do you guys have? Do you have usb debugging or anything like that enabled in dev settings? Every time I hook up it comes up with the dialogue box to enable data access. Whether I click enable or not it will not play anything stored on phone. I've had this confirmed by Huawei Australia. They couldn't get it going either.
I have all the correct permissions set for all apps including android auto.
Any hints?

In developer options I do have "Always prompt when connecting to USB" turned off and "Select USB Configuration" set to MTP. I don't get prompted for anything on the phone. USB Debugging is off. I don't try to play anything from USB though, just use AA, Spotify, and Audible.
Other than that, I do have an Automagic script that when car ui mode is entered, the screen gets turned on, Waze is launched, slide to unlock keyguard is dismissed, and wifi is turned off. I won't need to do most of this when Waze is AA compatible, but until then, I can't live without it. This script works about 90% of the time, still haven't finished tweaking it for 100% success. Worst case, I have to turn the phone back on, swipe down on the notification panel, then select waze from "Notification Shortcuts".

Seems this is possibly the issue. Whenever I connect usb it automatically changes the usb connection type to charge only. Won't let me change it to mtp, audio or anything else. Wonder if there is a hidden setting somewhere in emui that does this... Tried it in dev settings. Same issue. Charge only

I couldn't find anything else that I changed that seems relevant. I'm just using a standard USB to USB-C cable (Anker PowerLine+) plugged into the USB port in my VW Golf.
Did you change both of those settings I mentioned? If so, when you go back into dev settings does "Select USB Configuration" still say MTP, or did it default back to Charge Only? Maybe you have to reboot after? dunno...

I changed those 2 you said but as soon as I plug in the Huawei cable (thought maybe it needed the Huawei cable) it changes itself to charging...
I'll keep looking into it. Thanks for your help though. This is obviously the issue.
I'm having the same issue in the US version on a 2017 VW GLI. My last two phones worked flawlessly.

Mine goes to charge only as well however my android auto is working perfectly.
It connects and on the phone side it seems fine but the head unit screen goes black and doesn't do anything.
Hi.. Is there anyway to prevent WhatsApp notifications showing up in android auto?
Mate 9 L29 - B156 in a Seat Ibiza 2016.
Android auto working fine.
You have reviewed android permissions, or if Google app or maps are set to close when the screen is turned off And enable activation?
In my old zenfone 3 that was the problem
Did any of you guys tried to enable the USB debugging mode?

JA! This was first thing, but no success.
I am also disappointed by Huawei customer care. They just point at Google and say it is not their fault.
Does anyone know how to log / where to find the log when "Force logging" is enabled in dev options in AA?

Open android auto, go to about, tap the Android auto title 10 times, you will see a toast saying your developer. Now from the 3 dotted menu on the right select developer options locate force logging and make sure it's enabled
