[Q] USB not recognized

Hi all,
My Droid charge decided to do something weird today; it no longer will USB mount! This problem is particularly bad because, while I can put the phone in download mode, my computer will not recognize the USB and ODIN (1.2 & 1.8) cannot wipe the phone.
Any suggestions? I really need my phone back, but I'm not sure what to do.
Tried reinstalling the USB Samsung Drivers, using the original data cable, and two different computers (Win7). SD card will mount in an external drive (aka without the phone), and the phone will charge via USB. I have the most recent form of CWM on it, and the EP4P debloated and rooted rom.
Thanks,
frak

That happened to me a while back. Mine had the added bonus of going into desk dock mode and staying there. It was a hardware issue with the USB port. It would charge, but nothing else. Mine did become intermittent though, and cycling the cable in and out seemed to help it some, but ultimately, I had to send it in for replacement

What cable are you using? I accidentally grabbed my charging-only cable the other day and didn't realized it only had the wires for positive and negative. No data pins.
Is it the cable that came with your Droid?

Another thread similar. Check it out and try some.

Had that yesterday. A different port worked fine for me. Maybe a couple of power cycles will do the trick.

Can you point me to the drivers you installed? Thanks in advance.
I am having same problem and going nuts. I have Galaxy S2. I CAN connect to windows and Kies when phone is booted up but can not connect while in download mode. On Andoid System Recovery <3e>, I tried to do factory reset and wipe cache but no vain. Still getting usb not recognized.

[Q] Need a Rom to flash in Android System Recovery

Hello. Newb here so sorry if i make lots of mistakes.
I have a Samsung Galaxy Note 10.1 (2012) n8010 that is stuck in a boot loop, only flashing up the Samsung note logo then rebooting.
I am able to get into Android system recovery and Odin mode on the tablet.
It reads the SD CARD.
I have wiped data,factory reset and wiped cache partition.
It will not connect to my PC (tried 3 different ones) via the usb cable. I have the drivers installed via the Samsung_Galaxy_Note_ToolKit but the PC's just say USB Device Not Recognized unknown Device Hardware device not connected to this computer (Kies is not installed).
So i cant use the PC to connect to the tablet to use the tool kit or ODIN to flash any recovery.
Does this mean its most likely a hardware problem?
Faulty cable?
Is there a STOCK/CUSTOM ROM that i can install using the ANDROID SYSTEM RECOVERY via a .zip file that i can put on the SD CARD that will pass the signature verification to set it booting normally?
Thank you in Advance for any advice or suggestions.

I have seen this condition a lot lately.
How old is your Note 10.1, do you have the original factory cable and what condition is it in?
Not being able to connect to your computer is not good.

I bought it 0ct 2012 so its passed the 1 year warranty. Haven't contacted Samsung yet.
If it becoming common then is a mass complaint of all the effected units in order?
The cable is the original factory one. Seems fine on the outside. It charges normally and the PC sees it connected but just as an unknown device.
Tried to connect with the Kies (after downloading and installing) not still no connection.
Might try connecting it to my sisters Mac book tonight.
Buy a new cable?
Any repairers in the England sussex area to fix if worst comes to the worst?
Thanks

i used different cables and pcs but still not recognised
yesterday i used odin with those options :
BL/AP/CP/CSC and checked
Auto-reboot
F.reset Time
phone EFS Clear
Phone bootloader update
it has taking some while to execute but after that my phone was working and detectable again by my pc the problem was resolved for a couple of hours, in the evening the problem occured again.
and i have tried the process again the same why but no connection at all.
i don't know if its a hardware problem or software related problem
because the usb work when i m in restore mode (Odin mode) otherwise no.
Its an advance problem i already check all about usb / cable and pcs related problem.

Problem resolved
I sent my S6 to Samsung SAV it take them 4 days.
they doesn't give me proper answers on what they have done but i saw that my mini-usb plug is new so i expect that they got this part changed accrodingly the samsung has no sign of damage its a clean operation.
Its now detectable. It was indeed a Hardware problem

i have the same issue but in a g928f
today i changer my lcd with the micro usb flex
so all is new except the main board and still is not recognised at any pc with any cable.
i am really starting to feel very sorry for this phone.
odin does not see it at all even at download mode.
i don't know what else to do.

Software or Hardware Issue
I have a s6 920t that I am suppose to pay for at the end of the day. I got it from a friend who bought it while overseas. The only time my computer detects it is in download mode/odin mode, I hear the sound and I see it as "Added". When I try to connect any other way I don't hear the sound my laptop makes when it has detected a new device also otg cables don't work. I just simply want to know if this a software or a hardware issue? Software I can fix but if it is hardware I don't want to waste my money. Please anyone reply as soon as you can so I can decide what to do.
Thank you

I have two S6 Edge and one of them started doing this (phone only appears on USB when in Download mode). When swapping the motherboard between the phones, it works. So the problem isn't with the motherboard, but the USB connection module attached with the ribbon cable... There must be a chip on the module which gets locked somehow and replacing the board is at least one way to fix it. Hopefully someone finds another method without replacing the charger board?

G920F, USB MTP, FASTBOOT not working anymore.

Hi all,
So I have a strange problem, a while back I discovered that I can't connect my S6 to my computer and or other computers, whatever usb cable I use the device is not detected at all. and only charging works.
I already tried more USB cables and validated they work with other devices, I also discovered the USB is not detected in fastboot mode, so I can't flash any images anymore over USB.
I also discovered that I might have flashed a wrong stock rom a few months back and I never tried to connect it to the USB in the meanwhile, when I trace the baseband version it says it's Asian..:crying: And this device is a dutch PHN. The device has ADB working over WIFI and root enabled, it also has TWRP installed and even there MTP is not working!
However i'm afraid there is no way I can flash a stock rom back to the device without a working fastboot, unless there are flashable zips.
What do you guys think?
- MTP does not work
- Fastboot works but USB is not detected (odin, device manager etc).. with all kinds of cables.
- ADB Shell + Root Works (Only over wifi)
- I got a full backup of all partitons, created it with TWRP.
- It's stull running android 5.1.1
Best Regards,
Toetje

I can´t belive it, someone who has the same problem then me. A little wierd is that I got 2 phones here.... Got my S6 which I´m using atm and some days ago a friend gave me a A5. Actually the A5 has exactly the same problem and one more problem is, that the "Home Button" of the phone is not working. No chance to root it at all.
It was like this.... I came back home with the A5 and first I thought about was rooting it. Restarted and tryed to go into "Recovery Mode" which wasn´t working, same as going into "Download Mode". So my first thought was that some of the buttons arn´t working. I was right, it was the home button which is without any function. My next idea was rooting over Laptop with Odin. Enabled USB Debbuging, connected a data cable..... and usb connection was not working... only charging!
After like a minute of trying and no success I wen´t eat first. When I came back i tryed again and USB Debbuging asked me to accept the Laptop. (Till now I didn´t thought about that it could be my first and my last time I will have a working USB connection.)
I wen´t into "Recovery Mode" thought about restarting cuz I wanted to go into "Download Mode". So I restarted and that was FATAL.... since then I had no chance anymore till yet to get a working USB connection. No matter which PC, Laptop, USB / Data-Cabel. And since the "Home Button" is not working, I don´t even know how to get Root.
Right now I´m asking myself if it could be a Firmware related problem?! I mean, when my friend gave me the phone there wasn´t the newest update installed on it so I just updated it. It´s a A500FU running stock Android 6.0.1 newest DBT Firmware..... and also I´m not able to change it without having a working USB connection.

I ordered a new USB port board, will let you know the results!

Any results after changing the usb port?

Did fast charge still work for you? And this replacing the USB port work? I think this is related to a broken USB ic. For me replacing the USB port didn't help

Sometimes it's a bad charging port and / or liquid damage to the charging port.
If your home button clicks but does not work it could be liquid damage near the home button. Same goes for power and volume buttons.
I just fixed a S6 edge plus yesterday power button not working, liquid damage all around power button area, fixed burnt components and corroded pins.

Strange behavior and restarting [N915FY]

The phone was running 6.0.1 MM stock when I got it.
It booted normally and worked for a few seconds, everything worked fine and after 10 - 15 seconds it froze and rebooted and it kept on doing that until I removed the battery.
I connected it to the PC but it wasn't detected by odin (the drivers are installed correctly). I got this message from Windows: "Unknown USB Device (Device Descriptor Request Failed)". I tried a few times and everytime this happened.
I kinda gave up but I tried to connect the phone to pc one more time and it got detected by odin like nothing has ever happened.
I flashed Lollipop but it was restarting at the end of the bootanimation.
I bought a new battery.
The "Unknown USB Device (Device Descriptor Request Failed)" problem still exists.
Somehow got detected again so I flashed TWRP and while in recovery the phone "works fine" even with the charger unplugged.
The phone is still useless tho.
Flashed back MM stock and the issue still exists.
I already ordered replacement USB port. It will come soon so i will check if the detection problem is caused by broken USB or software issues.
Also there is a small probability that my "new" battery could be dead too.

hey, bro, i have SM-N915G.
From last few days, i am facing the same issue.
All of a sudden phone keeps rebooting itself until I connect it to the power supply.
after connecting to the charger it gets booted properly.
please help me if you found any solution.
