Moto G 2nd gen XT1068 USB and OTG USB not working - G 2014 Q&A, Help & Troubleshooting

Hi guys hopefully someone can help me.
I have a Moto G 2nd gen that has a busted usb port.When I connect it to a pc I get a "device not recognized" message.Ive installed the motorola usb drivers but that doesnt make a difference.Ive enabled usb debugging and set it to media transfer with the pc but that hasnt helped either. OTG usb doesnt work either.All of this started one day when I was still running a stock rom(rooted obviously) so I tried flashing CM 12.1 to see if it would help but it didnt.Obviously now I cant flash stock firmware becuase hey the usb doesnt work.I cant be sure but I think it might be hardware issue.Ive sent it to a repair center and they cant find anything wrong with the usb port istelf,so now they are checking the mainboard for issues.
Im still waiting for them to come back to me so I thought Id ask here on XDA and see if I could solve this with help from you guys.I appreciate any help you guys can offer.
Regards
Ali

Nothing can be made but flash over stock rom. If problem persist, that's hardware issue 100%, no mather what kind of. Maybe they will have a spare board to replace yours. Or desoldering for new port will help. See what they answer you.

Ive just heard back from the tech guys.Its not good.They dont know what the problem is .Theyve tested the usb port and that seems fine.The best explanation they can give me is that the IC that controls USB on the mainboard is faulty,they tell me that this usualy occurs when a faulty usb cable is used.Oh well at least I have my moto X play.

[Q]Hardware bricked USB connector or just software prob?

Hello,
few days ago I've got my USB OTG cable. So, when I connected this OTG cable to my USB HUB through USB cable with 2 sides of type A port (pic here : http://www.cyfronika.com.pl/art93/kab120aa-l.jpg) to get power on HUB from USB port charger but nothing happened on phone with flash storage, any notifications or something. Then, when I wanted to transfer some files from my computer to sdcard. I've connected USB cable but Windows 7(32-bit) says that my device can be damaged or something (code 43). I've searched about this and found this http://pcsupport.about.com/od/errorc/a/code-43-error.htm . I've used http://forum.xda-developers.com/showthread.php?p=21503469 for setting up the OTG and for kernel too.
Well, I've followed this tutorial but the error still appears. Tried on 3 computers with different cables and different USB ports.
So just tell me if it's software problem or I must do something with this.

(bump) can anyone help me?

(bumpin' like a crazy) Please, anyone have solution for this problem?
So the general idea is, you're trying to let your phone connect to other hardware while the phone is the host, right?
Now you're trying to connect your computer to your phone again normally and it's not working? (normal usb cable)
For one, there are a bunch of errors in the log you posted, thinks like
Code:
W/PackageManager( 353): Unknown permission android.permission.ACCESS_SUPERUSER in package hu.sztupy.android.usbhostcontroller
That might be a problem, I don't know. Perhaps you're better off asking the dev of this mod about these errors. Maybe there's something you forgot or wasn't mentioned in your guide that causes these?
Have you also considered the possibility your phone is now *always* trying to be the host (which is not going to be something a pc likes)? You're saying you can't properly connect with your pc any more, but can you connect with another device (usb stick for example)?

Yes, It was the general idea when I've bought OTG cable.

Yes, tried with 2 Nokia cables and one stock from Samsung. Windows is always showing code 43 ;/

Well, I'll try to contact with @sztupy (http://forum.xda-developers.com/showthread.php?t=1468531). Anyways I think I haven't forgotten what I wanted to write.

I've set default settings for USB Host Controller app. But no, I can't connect another device. I'm in half way to download Linux, maybe on it everything will be working properly.
Anyway thanks for your reply, let's see if it will be working on Linux ;f
//EDIT : Same problem on Linux. Device is not recognized.
(bump) Any ideas?

ADDED MORE LOGS.

Bricked Moto X. $20 in bitcoin if you can help me find a solution for it.

I've spent lot of time reading and trying different ways to unbrick my moto X xt1052, I can't even remember how I got it bricked, but I think it was when trying to update Cyanogenmod to Lollipop. Anyway, at this point the device is detected by computer for couple of seconds as a HID device and get disconnected.
Please if you have some ideas about what should I try, I would rather pay you instead buying a new main board.
No need to pay anything. We are here to help each other. Try with different USB cables an different USB ports. I do faced same issue with my nexus 4 nd Samsung Galaxy s. It's like a loose connection on port side or the cable sleeves. Give it a try.
Don't forget to install moo drivers, when try on different computer.
Press thanks if helped

usb camera and bluetooth stoped working on laptop

Hi, I m an IT guy that has run out of ideas. I would like to ask you some questions about a (probably hardware realted) problem that i have. All started suddenly , from one day to another all usb ports, camera and bluetooth stoped working. I dont really care about the bluetooth and the camera, the only thing i care about are the usb ports. I 've checked them with a multimeter (only the pins that provide power) and the strange thing is that they do provide power. If i connect something like a usb flash drive , the led flashes (stays on , doesnt flickers) but nothing happens. I am sure that's not a drivers problem because the laptop doesnt even recognize them in UEFI nor CSM. My UEFI does not have an option to completely disable usb ports, only to change from usb 2 to 3 (no change at all). I m sure it's now a power problem, i ve reseted the bios even by the motherboard jumper.So the question is , what it may be? is it a motherboard malfuction ? Can it be fixed? Also , is there any possibility that for example the camera is faulty , or the camera cable , and shortcutting something? (i mean if i disconnect the camera and the bluetooth, is there any possibility that it will be fixed? ) thanks in advance.
p.s. also on the motherboard there isnt anything strange like a blown up resistor or something.

Though the Forum does not really provide PC/Laptop support unless it's related to the Android type of devices so there's really a limited amount of information regarding them specifically.
With that stated...
The following thread is probably the best place to ask this question.

Help, Mi A2 USB problem!

Hi, phone works OK, it also charges BUT doesn't connect to any PC (windows detects device with description error?), usb OTG not working either, only headphones using type c adapter. Please help, I'm using stock pie with February update, unrooted, blocked bootloader and with usb debugging enabled.
@egantz09
Disable USB Debugging.
Install this driver (and please follow the instructions):

Hi, Thanks for the guide, but I can't pass from step 6 in which I need to install the Mi Drivers but no PC recognizes de phone, not even in fastboot mode, see screenshot. Any other ideas? I can still charge it and listen audio trough the usb port. Thanks in advance.
Edit: I've hard reset the phone and the problem still persist.

Thanks for the update.
Go into Step 7, with the device connected, and install the drivers manually.
So, in this scenario, you'll right click on the device and browse to the location where you downloaded the drivers.
I need to know what happens if you try and install them manually.

Hi, I can't actually do step 7 because it doesn't recognizes the phone as an Android device like in the guide, but as an:
Unknown USB Device (Error Device Descriptor Request Failed) see attached screenshot.
Even when I select this Unknown USB Device and tried to update de driver manually, the installation fails. (see attached screenshot) .
I've changed cables and tried on different ports of different PCs. Same result. Also by entering Developer Options and accessing the USB settings won't work, there are all greyed out.
@egantz09
Thank you for your efforts and feedback.
Based on the details, I would strongly suggest you initiate a return. You've taken all the appropriate steps, and then some, to address the problem but it's obvious the issue exists with the device hardware.
I am happy to provide further instructions but what concerns me is the fact you've tried multiple PCs and multiple cables.

Hi, I can't return it so I already ordered online a replacement Port Board from aliexpress.com, so I'll check back in 4-6 weeks, thank you very much for your help.
did replacing the port solve your issue? I have the same problem
---------- Post added at 07:21 PM ---------- Previous post was at 07:21 PM ----------
cant even force edl mode
Sadly I'm still waiting for the replacement to arrive...I'm in Cuba. But other people with similar problems have solved them by replacing the USB port. Good luck.

if you followed all of the instructions and steps in this post and the problem continues, then you should return your phone.
I already changed my USB port. My warranty is void
If your phone was in warranty you should have returned it, changing the USB port was your final option. Now you should take it to a service center. Good luck,

I replaced my usb port today, still no luck, I tried 3 different ports (I bought 3), It charges with all of them but no USB connection to PC or OTG. I'm thinking its the mainboard. Could it possibly be the FLEX connector?
This is a big problem with 2 MI A2 for me
Since that problem i hate Xiaomi and never Xiaomi product to bey
I have the same problem ... My phone only charging when i connected via USB to the PC... I change USB board and i still have the same problem... I can't choose any options.. only charging.. any help how to solve this problem ? Thanks

I waited 3 months for my USB port replacement and it did the same thing, now I'm waiting for the flex connector, if that doesn't work either, then its a problem with the motherboard.
I ended up replacing the entire phone and a few months later this phone now has the same issue.. this is horrible. Especially with no USA support from Xiaomi. Its a "deal with it" situation.
But i believe the use of crappy chargers, debris getting into port, maybe Qualcomm quick charge modules design flaw could be sending unsafe currents or lacking proper temp regulation when charging,, is damaging something on the main board. I checked every possible software related possibility and tried every fix with no luck.
What i did notice when it happened this time, chargers were not staying connected, they would pop out due to debris in the charging port, also i noticed my phone got pretty hot using a Qualcomm QC enabled charger one night. Nothing else was suspected of generating heat, all apps closed, screen had been off.
I everyone... Where i can buy an usb port?? My A2 is not charging, trying at least 4 different cables and chargers,
Tks

Question Mi 11 not connecting to my PC?

Hello does anyone else have a problem with the Mi 11 connecting with a USB? I have the Asus Prime Pro X570 motherboard with mutiple USB ports, 2 usb ports on the front of my Corsair 5000X and every port apart from 2 will only charge the phone. The two usb ports connected to the ethernet rail the phone constantly connects and disconnects and the select file transfer, no action etc on my phone literally flashes and has seizure.
It can't be the cable because it works on other PCs. Also tethering works through USB. It's only when I'm trying to access the phones files?
Hello I Have the same Mainboard with the same problem and what can I say... For me the solution was an other pc to unlock the bootloader and flash a cfw. Then tested on my main pc and still nothing. Then tested my three other USB cables and with two it worked.
I have no idea why that is a thing. Maybe the Mainboard USB problem that had to be patched since 1.2.0.0?

Maybe it's an Asus problem but I brainstormed and was like wtf it's android. If you need to transfer files you can use an ftp client and do it over WiFi, but it still sucks cause I can't flash anything
I had the same problem but after I connected the phone to a 3.0 USB port the problem solved instantly.
