I'm having a weird problem. My 9t only connects through USB C to USB C. Don't prompt on USB A to USB C.
I've gone through every single process with driver installing to changing USB logic board.
Another thing is, i can connect my phone in recovery mode, but in fastboot mode, It's not detecting.
I tried on several Cables, devices, OS versions..

It all started when my phone didnt connect to the pc with my own microusb cable anymore. After lots of reinstalling drivers i tried another usb port, now the phone did connect. In a rush i started up odin to flash standard firmware so i could get my warranty for the usb failure. Then during the flash the phone lost connection again and hardbricked. I can only get it to download mode but the phone has the usb problems mentioned before again, i cant connect to odin/kies/pc. all pc's told me that the usb driver could not be installed
try removing all usb drivers with usbdeview, make sure that KIES aint running in the background, boot phone into downloadmode, connect is and as soon as you'll see the yellow com-port sign; hit start (with the proper .tar files at pda/phone/csc).
only one way to find out =/
Thanks for the help but the problem is that the yellow com-port sign wont come because the device isn't recognized.
You have download mode but no USB .
Remove existing KIES and all USB drivers reboot reinstall KIES and try .
Not work try on a different PC .
But unless you have fixed the initial error you are wasting your time .
Initial Error you said >>>It all started when my phone didnt connect to the pc with my own >>>>> microusb cable <<<<<<<<<<<<< anymore

Tried another cable and another computer, still no connection. I think probably an internal failure in the phones motherboard?
3 days ago i flashed my sgs with Ultibread v1.3
Today i decided to flash back 2.2.1 firmware, but all of my 3 computers (10 usb ports) couldn't recognize my phone.
Try to search any solve of this problem, but no one tutorial has not helped.
What did i do?
uninstall all of samsung usb drivers
clean register of all garbage with "samsung"
reboot my computer 3 times
download latest samsung usb drivers v1.3.2000.0 (25.jan.2011)
get out battery for 15 minutes
try plug in other usb port
take computer, wich never connected my phone, install latest drivers (see previous step) and connect sgs to him...
In all cases, the result is one: Unknown USB Device.
System can load and "debug mode" switched on.
Please, help me...
My PC forgets my SGS on a regular basis. When I plug the USB into my phone it is usually a good 50/50 if it recognizes it.
I have found the best way to deal with it is to reboot the phone while it is still connected by USB to the PC. When the phone comes back up with the USB connected, the PC always discovers it right away.
Also avoid connected through a USB hub if possible, that always gives me trouble.
Omg! Solved.
Ultibread v1.3 and, maybe, 1.4 got issue with check in debug usb mode.
And without this check - windows can't recognize phone.
Solution:
turn on debug usb mode in settings, then put out battery when phone is ON.
Then you can get in download mode.
Case closed

I don't know which rom you have flashed prior to your problem with the phone.
But if it was my phone the first thing I would do is to go into recovery and do a
factory reset, doing that just might fix the issue with not being recognized by your
computer correctly.
It might also help to uninstall all the usb drivers and kies from computer
then only install the samsung usb drivers for windows.
Good luck,
Have a happy merry Christmas.
I have a Samsung Galaxy SIII (GT-I9305), and here are my problem(s)
can't be detected by PC via USB (not showing on device manager, odin, kies, not even charging)
but it is charging when connected thru a charger
but it can detect my flash drive via OTG
already tried reinstalling correct drivers, tried different cables, tried different USB port, factory reset both from settings and recovery menu.
How can I fix this?
Also, I'm wondering if I can still attain root access/permission even without USB connection but thru terminal emulator?
Famaroot Aragorn exploit does not work.

Try and clean your usb port with soft tooth brush and alcohol, remove sim and sdcard and battery, then connect yr phone to pc holding power button and insert yr battery.
You can also try and update kies to the latest
Have you tried different pc?

i already tried it and still cannot be detected. i have a samsung win gt-i8552 and it connects to my pc just fine using the same cord and inserting to the same port. I was wondering how come it charges from a charger but not when connected to pc. and also it detects USB OTG but not the USB connection from my pc.
Hi all,
I know there are lots of similar topics but this is a little bit strange because I can't use adb and usb also.
Device rooted and TWRP 2.6.3.3 installed. I tried in different computers and cables but computers do not recognise phone. It just boots TWRP. Is there any way to copy files in the phone without usb and adb?
I have replaced usb port a couple months ago due to charging problem, now charging ok but pc doesn't recognise and says "unknown device".

why not?
you could look here: http://forum.xda-developers.com/showpost.php?p=52135024&postcount=2
also here for usb-otg: http://forum.xda-developers.com/showpost.php?p=61449330&postcount=23
see if any of those work
or just flash a newer TWRP and use MTP transfer
twrp has usb mtp function
enable it
I changed usb socket. Now I'm able to connect phone but it only charges when phone off.
