I am using a Samsung Galaxy J8 . My phone doesn't have any SD card. I was able to browse files of phone from my PC(ubuntu os) , even I could debug my app from android studio. But suddenly I am not able to do so. When I connect my phone via USB to my PC , it is only charging . What I did so far is following.
1. Enable developer option and usb debugging , changed default usb configuration to file transfer and image transfer and MIDI .
2. Restarted my phone.
3. Restarted my PC .
4. Change of USB cable and port .
5. At last factory reset .
After trying all above things , still I can't connect to phone via usb cable .
I think my pc , usb cable , usb port are working fine . Because when I connected another device , it works fine

Try connecting your phone to another PC/Laptop etc also change cables, if it works then it is the USB port on your PC having issues with the drivers uninstall the drivers from the system menu and reboot your PC. Important to note here is that doing so will also disable your mouse and keyboard so just tap the power key on your PC and it will shutdown.

Since the USB port is working it must be the USB cable/connectors see if you can replace it or test it with another cable, if the cable isn't the problem your USB port on the phone might be partially busted since it will allow for charging not data transfer. Something on the side, on my PC I need to unlock the screen to access my phone drive and SD card did you check for that?

He did not say open device center , he said open "Device Manager", you can open it from computer management in the control panel ...
You did say it said "device unrecognized" that means the pc is "seeing" it , just not seeing it right ...
When in device manager find ,the item that is this "unknown device" if you are not sure which it is, unplug it see what dissapears, and what reappears when you plug it back in, it may just be under usb devices or the similar ..
Then Uninstall that device, then unplug the phone, wait a few seconds and plug it back in ... also plug it right into the computer do not use a usb hub ...
Thanks watcher,i understand now i did not read it right,i will try Device Manager now.
Thanks

i have had several experiences with usb devices malfunctioning and causing that kind of error. and a few of those times i was able to isolate the problem to a faulty cable. but those were generic usb/miniusb cables (ie not supplied with the device... just available loose in the market). if its a cable supplied by the OEM, i doubt it would fail all of a sudden. but try swapping cables and see... good thing hd2 has a standard mini usb interface...
Thanks silenced i will try a different cable tomorrow thanks for your help

Hope this helps.
Install Kies .
Reboot phone
Start Kies
Connect Let KIES find phone .
Turn KIES off from taskbar .
Turn USB debugging on phone connect USB mass storage mode and let windows find driver .
That do work try all the other posts same subject for an alternative .

No go
Tried all of the above, still no go, could it be my micro usb port on the phone is busted? When i tried connecting as Mass storage it says usb cable is connected, pls remove cable.

No thats just incorrect user settings .
Remove cable go to settings Applications Turn on USB debugging .
And?or turn usb mass storage mode on via settings Wireless and network USB settings then connect cable .

I'm getting this problem once I'm in Download mode. It's worked before... why would it stop?
Any tips?
I have the same problem
I seem to have the same problem I connect my phone via USB and get a USB Device Not Recognized message but MTP application opens on the phone. This has only just happened I have had it working before since I had the phone on 2 computers and have tried to different cables now it does not work on either computer. If any one has had any luck I would love to know how you fixed it.
Samsung Galaxy S2 - USB Device not recognized.
Hey Guys,
I have the same problem. I've even tried going into "Recovery" Mode and then running odin.. Still no luck. It just does not recognize the phone.
I tried a different cable but still no luck.
Guys,
i had had the same problem until i started to use the original USB cable(came with the phone).
Have a good luck!

Got the same usb problem, different pc's, driver, cables nothing works.
After three month of use no Kies Odin ore mass storage us....big problem
any news info on this? seems to be quite common, though I only get it with stock roms, custom roms dont seem to have this issue
Cables Guy; I'm trying to figure out if I'm having the same problem as you. Does your phone charge when plugged in? Because mine does not.
i think in your case it might be the usb port in the phone itself, if nothing that you plug works well.
I believe there is an issue with kies/MTP and windows drivers for the rest though.
For me my phone doesnt get detected o nmy onboard USB but it does on the usb3 pccard i have.
any good news to solve this problems?
i got the same problem and worst case is my phone cannot detect sim
I had the same problem.. I just switched back to the original cable that came with the phone & problem was solved..

whats your phone kernel? and are u able to connect to pc as usb storage? or did u flash anything weird before?
Hi,
I think the usb port on my sgs2 is f***** It will send a charge to the phone, but will not recognise it.
I get error on my vista laptop as :
USB DEVICE NOT RECOGNIZED - One of the usb devices attached to this computer has malfunctioned, and windows does not recognize it. For assistance in solving this problem, click this message.
I have tried reinstalling usb drivers on kies and put in debugging mode etc. I had a problem with the phone not charging around christmas time, so I cleaned the usb port with a cocktail stick, that got the charge working, but it has not picked up usb mode since. So I cant connect usb storage or to ODIN, let alone KIES.
Does anyone have any advice/suggestions as to what I could try, I really dont want to send it back for repair and be handset less for a month!

I am Sure no problem with your mobile. May be problem with computer Hardware or Drivers.
can you try different USB port or you can different computer also.
If you dnt have another PC , uninstall all samsung drivers & kies and reboot the PC.
Just connect as USB storage . USB storage not require any special drivers.
Also use the original usb cable. I have two different cables and only original one works.

I have the same issue, if your not rooted just Send it for repair under warranty but if you are you'll have to flash a stock kernel to remove root first and use a jig to reset your flash counter

Had the same problem, http://forum.xda-developers.com/showthread.php?t=1425128my cable was the culprit.
Mobile Odin for flashing and Remote Web Desktop/Root explorer for SD access will tide you over.

Make sure:
The selection of AP/BP connection behavior
when connecting your phone (as a client), with a USB cable
to a PC host, is manually set in the PhoneUtil (PU) Menu.
This sets the behavior of your phone when connecting it
to a PC. You can select wether you like it to act as a
Modem or PDA, o via USB or UART port. The PU does not
seem available from the ServiceMode menu.
Dial: *#7284#
Code:
UART:
[o] MODEM*
[ ] PDA
USB:
[ ] MODEM
[o] PDA*
* is default SGS2 setting.

cable is ok .. tried two cables no luck .
tried on another pc no luck .. i have 2 pcs earlier i had no issue in using adb/mass storage on either ..
i tried clering the /cache partiton from recovery ..

I just bought an old Galaxy S3 SHV-E210K android 4.4.4. Everything work fine, but I can't connect to my computer through USB port. When I plug in USB port, my phone only charge, have none notifications about USB connection ( same as my PC).
So i tried:
- Hard reset my phone
- Change my cable, USB port, computer ...
- Install, reinstall kies with drivers
- USB debug mode on, off
- Try to use *#7284# and *#0808# but nothing happend. ( for more information I can't use *2767*3855# too)
- Try to root with kingroot, ROMmanager, ... but can't. It seem like my phone block all these apps
- Try to find OEM unlocking but there's no option in developer options
Please help, i read all articles but nothing solve my problems I'm so hopeless
Have you connected the phone to the motherboard usb port and then installed kies then stopped the kies processes?. You can also uninstall the kies program while keeping the drivers.

No i havent. After i had installed kies with driver, i pluged in usb port. Nothing happened
Have the phone already connected so it can find it correctly..
If it still isn't detected by the computer, the USB port could be damaged.
