I have an AT&T Z998 phone running Android 4.1.2 that is rooted. I bought an OTG cord and nothing I plug into it will detect. Running an app called USB Host Diagnostics told me that the Android API supports it but does not detect the device.
I plugged the cord into someone else's phone and connected it to a male to male connector to plug it into my computer to see if it detects it. It detected it and started charging the phone, so I know the cord is not defective, but other devices such as a mouse, keyboard and flash drive are not detected (also, my computer doesn't detect my phone).
I've also tried it with a Galaxy Tab 2 7" tablet and my computer detected it but would not charge.
TL;DR - Device not detected with OTG cord but has manufacturer support for OTG.
Any help would be appreciated. Thanks!
Online I've seen people using a USB OTG cable on the Samsung Galaxy S6 but when I try to do so on a Verizon model it does not respond to keyboard or mouse input.
Has anyone else tried to use USB OTG?
I used my OTG cable to hook my verizon s6 to my external hard drive last week. Everything worked fine. Check your language and input setting maybe?
Well the problem is that there is no response at all. For example when I connect the mouse to another phone via the cable the mouse light turns on, connecting it to the S6 does nothing.
Are you on 6.0.1 as well?
I am currently on 6.0.1. The other thing to check would be the usb options in the notification area when you plug it in, if that shows up.
That's what I'm hoping for as well but nothing shows up, very odd.
Have you tried using your OTG cable on another device? Or using another peripheral? Do you plug in your device to charge it? I'm just trying to think of all the possible things that could be awry.
Well so it worked fine on a Moto G and X and I had only tried a keyboard and a mouse. I've now tried a USB stick and it suddenly works on my Galaxy S6 as well. Keyboard and mouse now suddenly work as wel... I'm starting to think it must have been a loose connection due to my phone case or something cus I can not think of any other explanation as to why it suddenly started working. Regardless, thanks for your help!
So I've had my S7 for around two months now, and all of a sudden fast charging just stopped working. Thought, oh, must be using the wrong cable (have loads of them micro USB cables floating around)
Now I'm certain I'm using the official Samsung fast charge plug and cable that came with the phone, and still no fast charge. When I try to plug into my Windows 10 Desktop or Laptop I have a message that says the device can't be recognized
Phone has already been rooted and flashed with a custom rom. Didn't think that was the issue as it wouldn't even show the mounted storage in TWRP, or identify the phone in ODIN.
Now I've flashed back to the stock rom that I made a backup of when I had the phone, and I still have the same problem!! Can't access internal / external storage using the supplied USB cable and can't fast charge.
I'm thinking the USB port on the device is just knackard.. but really, I've looked after it so well I fail to see how this could happen, unless it's a common fault.
Might just get a wireless fast charger, but do you guys have anything else I can try before giving up on the USB connectivity?
Cheers
try to connect to a different pc, if same it means your usb connector is faulty
Sounds more like the cable is bad tbh, you won't get fast charge from a PC USB port, only from the Samsung charger
But if the device isn't recognised by the PC, and won't fast charge from the charger, the common thing between them is the cable
Possible it's the phone USB port, but more likely the cable is bad
Afaik certain cables can not fast charge either, so chances are the ones you have lying around that are not the official cable can not support it
Genuine Samsung USB cable is white with the USB port symbol on both ends and the phone end has two small ridges to grip when inserting and removing it, should help identify it
Yep I'm using the official cable and fast charger
I'm trying to fast charge via the fast charger and not USB. Only trying USB to access the internal / external storage.
Tried on my desktop and laptop and both have the same issue where my old HTC m8 connects without any issue.

To fast charge I've tried the original Samsung cable with the fast charge plug.
To connect to the PC I've used x3 different cables that all work with my HTC one m8. With all of them I get device not recognised. Already tried installing Samsung switch and reinstalling drivers which didn't work.

I mean for the HTC, does the Samsung fast charge cable work to connect to the PC?
Does sound possible the phones USB port is faulty if you can't get any connection at all to the PC with multiple cables
Try changing the USB mode in developer options
Networking > Select USB configuration

Yep the genuine Samsung cable works when connecting the htc to the computer.
I've tried enabling USB debugging and switching between charging, MTP, PTP, RNDIS, Audio Source and Midi.. all of them come back with the windows popup

Unfortunately it is starting to sound like the phone is at fault
Still under warranty? (KNOX 0x0)

Unfortunately not. Well it's been rooted and flashed so I guess not.
Ordered a wireless fast charger so hopefully that will see me through and WiFi network for file transfers.
I reckon the USB port will need replacing but I'm not really inclined to do that myself.
Just noticed you said you flashed back to stock using a backup you made
Have you tried stock using ODIN and 100% stock files, using CSC to reset?
My dad has a5 2016 with the same issue, and no warranty. I bought flex + connector , replaced it and still nothing. No fast charge ( it takes cca 4hrs to charge it fully ) and no usb connectivity. I gave up on that
@ClowsTyle
Any luck? I seen your recent post in another thread and it sounds like you tried to replace the USB but that didn't work.
I'm having the exact same issue now. Device suddenly stopped fast charging, Windows does not recognize it when plugged into PC. I ordered a new cable to double check and also tried on different computers. I also tried reinstalling drivers, but nothing has worked.
Hi my is doing the same thing no Fast charge and no pc connection, did anybody find out what happen with yours ?
You have to change power ic s535 for s7 edge.
When usb gets moisture power ic will damage.
I have same problem my phone charging 0-100 6hours but ı install notorious kernel and it takes 3 hours it is better than 6 hours
Same Issue
I've had the same issue for the past 3 weeks now and I've tried everything I know...
1. Tested cable and charger with another S7 and they work fine.
2. Factory Reset.
3. Changed the USB port chip.
4. Turned on "Low Battery Dump".
So far, the issue hasn't changed.
was this issue solved?
I´m having same issues whit my galaxy s7 active, I can not fast charge my phone no matter what cable I use, then noticed that evrytime I plug it to any computer it says the devicescan not be recognized, I´m about to buy a new charging port and install it, but I want to make shure this is not a software related issue.
I´ve tried several cables and several laptops/ pc´s
I´ve factory reseted my device and turned on low battery dump, wiped cache partition, and problem still there...
The charger could be faulty/damaged did you try a different charger?

Dial *#08# and select the first option (mtp and another option i am on a custom rom that seems to not have the *#0808# setting
I also have the same issue with my phone the phone charges but not recognize and also tried to change settings on phone and nothing? And my other samsung phone works and nothing wrong with USB tried to install smansung drivers on PC and still same issue.
I tried a different USB and nothing works and different ports on my comp.
My ports works with my other samsung phone so not sure why not with the S7?
Is the USB faulty?
Does any one know a reason why a computer won't recognize a Galaxy S8+ when plugged in USB. To me its clear that drivers are messed up on the ZBook, but I don't know how to fix it.
I have two PCs, my wifes laptop and this HP ZBook x2 G4. All three of the other devices recognize the S8+, but the ZBook wont. I've gone into S8+ settings, turned on developer mode and turned on USB Debugging with no success. I've tried a USB C to USB C cable, as well as the USB 3.0 to USB C able that comes with the phone. Still nothing.

USB 3.0 has played much havok with S8 most recommend a 2.0 hub and seems to solve issues some of the time

First off, thank you for your feedback and your time.
Idk if thats the issue in this case. My other two PCs have no problem reading it via USB 3.0
But lets say the USB 3.0 havok IS the issue here. Does the USB 3.0 havok apply to USB-C to USB-C? My ZBook (the one having issues) has two USB-C ports. But even when my S8+ is connected to my ZBook via C to C I still have the problem. I figure if the "havok" is strictly related to USB 3.0 and it still doesn't work with C then maybe my problem is something different, unrelated to the USB 3.0 havok.
I REALLY want to connect my S8+ to my ZBook via USB-C to USB-C, so that I can use Sidesyc smoothly.
My guess would be the usb 3 driver on your laptop, perhaps try to find an updated usb3 driver.
The fact that your other two laptops see your S8 suggests that problem is with the laptop rather than S8+ or usb cable
Will look into it! Thank you!
Hi, Google a program called USBDeview.
Hello, I have an OnePlus One with LineageOS 18.1 and I'm trying for the first time to connect a pendrive to it, throught an OTG adapter.
I insert the pendrive and nothing happens. I tried several devices but it can be detected by the phone.
Since not even the light of devices turns on and since the same pendrive with the same OTG adapter works in friends' phones (I tried Xiaomi, Oppo and Samsung), does it mean that the OTG feature of USB port is broken at the hardware level?
