USB connections acting very weird. - Galaxy S II Q&A, Help & Troubleshooting

So my USB connection was fine just the other day.. now its not.
When I connect it to a computer or charger, mtp connected shows up. It only shows up when plugged into the computer, or when the battery is 100% on charger.
When I connect sometimes USB connected briefly comes up but never long enough for me to mount
I have checked the USB debugging mark but it doesn't change anything.
What can I do? It was working on the same firmware the other day...
Please help!

It now says mtp connected, but the computer doesn't recognize it. What is mtp and what can I do?

Just tick USB Debugging (go to settings, applications, development and tick it)

Tried that. No luck!!!

Try updating .net framework on your pc.
Also, manually point your device manager to install USB driver for samsung.
ADB should help you get the right drivers.

I'm on a Mac so it shouldn't be a problem, because Macs don't need drivers right?
I used it the other day with no problem.. now this!

Have you ticked USB debugging off rebooted phone and ticked it back on again? MTP isn't supposed to be on if USB debugging is.

[Q] Phone not recognized by Windows anymore

It happend after I flashed JK5 (I lost track with so many updates)
The phone is not recognized by windows anymore, cannot access odin or anything.
I have another vibrant and is still working so drivers are installed and everything.
The phone does recognize the connection, lets you choose, can get into download mode, but is just not being seen by the PC,
Since the other vibrant connects fine cable is also right, it is a problem strictly with this phone.
I tried flashing other roms, modems, and so on via CWM but problem is not solved.
Any help or ideas will be appreciated
I had the same problem. Someone said try usb debugging, & it worked like a charm.
Applications/development/usb debugging. I hope this helps.
Thanks, I tried that, and all the options for pairing without success

If USB debugging is enabled, it shouldn't give you a choice of usb connection mode. Make sure your USB cable is unplugged when you enable debugging, or else it will just tell you to unplug and try again.

[Q] USB debugging cannot be disabled

Hi.
Just bought Galaxy Ace for my daughter and faced with the same problem. it's at official 2.3.3 firmware, and each time i connect it to PC via USB - it enables the USB debugging. I tried disabling it in Settings->Application->Development when phone is disconnected - no luck.
Strange, but i don't see a "USB connection" option in Settings->Wireless and networks... it's there on my Galaxy S thou... May it be an issue with Ace's official firmware?
Update: flashed VillainROM-1.0 and still having same problem.

There's only a "USB Debugging" option, which, being disabled, gets automatically enabled again each time i connect the phone to a USB cable.
So what is the problem if it's enable? And Ace don't have "USB connection" option in Settings
Sorry, I thought it's obvious: with USB debugging always enabled - I've no possibility to connect the phone to PC as a disk storage or to connect it to Kies/PC_Suite

NO, is not obvious. USB debuggins doesn't botter your usb connection at all since you hace to activate the disk storage after you connect your SGA. Look on status, there's a message that tells you that you have to click there to activate mass storage. And on the other hand, KIES recognizes SGA after a few minutes, just wait a little longer.
i have the same problem. mass storage only works if you have the samsung drivers installed. if you connect the phone to a different PC that dosent have the samsung drivers it will not recognize it. if you disable Debugging so that the computer would detect it as a mass storage, once you connect it, it automatically enables debugging again. if you disable it while connected, it goes back on automatically.
i'm running 2.2.6 but i've always had this problem since 2.2
using windows 7
anyone can help?
USB mass storage worked fine for me on multiple computers without the drivers installed and with debugging on. There is no reason why either of those things would influence your connection. The problem is far more likely to be with either your computers settings or your usb hardware.
i tried on a few different computers, same problem. i guess i'm stuck :/
thanks anyway

[Q] USB will not connect to PC

Heres my issue, when I plug the usb cable in it doesnt connect to the PC. it tries to connect but then Windows say its disconnected.

Does anyone have any suggestions? I have tried multiple cables and 2 different PC's.
Thanks for any help!
Does the usb menu come up on the phone? Select storage device.
Reinstall the drivers from Moto.

Galaxy s3 i9300 only charging via usb but not mounting

Bro's I have a galaxy s3 32gb gt i9300 with stock 4.1.2. When I connect the phone to my laptop via usb (laptop is also Samsung) I hear a beep sound on the cellphone and it begins to charge. However, I see no options and no usb connected 3 pin symbol in the panel of phone and nor is there any other option like mount cellphone etc. I do have latest version of Kies installed on my laptop but even that shows no device connected. Please help guys I have spent a bunch of hrs trying to figure out how to get it going but eventually had to register on this forum for help :silly:
Tried a different cable? Usb uses fewer pins to charge than to connect to a pc. Perhaps the cable is damaged (or usb socket).

Much thanks for the quick reply.... No I don't think the port or the usb is damaged. Further, I'm using the stock usb cable provided with the phone. Any other suggestions?

And yes tried different usb cable, plugged it to different pc's, manually downloaded drivers from Samsung but still the dawn thing doesn't work
Edit: just now tried connecting a different cellphone using s3's usb cable on the same usb port and that works fine. So I guess that confirms both the cable and the port are fine
By port, I meant the one on your s3...
Check its clear. If it is, factory reset. If its still a problem, send for repair

I'm sorry for my quick scan on the thread if I miss something.
Maybe you should try go into recovery and mount USB in there to see what happens or try download mode as well (in this case, with download mode you can see whether USB works or not, if it works then means maybe problem with ROM, so you don't have to send to repair because software issue is not really a issue here, and if it doesn't, then download flash won't start so won't affect on your warranty for flash counts )

I had this problem before with a new brand cable, i just solved the problem buyin a usn charger for Cielo cards.
amazing.
Solved
I tried everything possible....
uninstall drivers. reboot laptop. install drivers. reboot laptop. plug in phone. no sucess.
put phone in download mode and plugged in. no success.
tried on different laptop running Windows 8 and Windows XP. Still no success.
Then i read about this somewhere...
said uninstall drivers. reboot laptop. install drivers. reboot. make sure USB debugging is OFF. Plug in phone. Switch ON USB debugging. Laptop should now detect the phone. But that didnt happen either. No success again.
Also read....
Go to phone dialer.... dial *#7284# to access PhoneUtil > "Qualcomm USB Settings" > set it to "MTP + ADB" .... phone will reboot. Then connect via USB and everything will be ok.
Unfortunately....
dialing *#7284# to access PhoneUtil did not show me Qualcomm USB setting.
It gave me 2 options:
UART> Modem or PDA (here Modem was selected for me by default)
and
USB> Modem or PDA (here Modem was selected for me by default)
I left UART as Modem itself.... but changed USB to PDA. Then click "SAVE and RESET" button.
My phone then rebooted. Once my phone rebooted and i was on lock screen/home screen.... i connected the USB to my phone and voila... my laptop detected my phone as GT-i9300 and show both my SDcard and extCard :good:
Give it a shot and lemme know....

Does #*7284# give you the following:
------—-—-------------
UART
-Modem <--- selected by default
-PDA
USB
-modem
-PDA <--- selected by default
???
If under USB, modem is selected by default, then change and select PDA.
Leave UART value to remain as modem itself. No charge here
Or worse comes to worse...
While keeping phone connected to laptop, enable USB debugging and see what happens.

OK...
So at the moment your PhoneUtil settings are UART>Modem and USB>PDA right? Leave it at this setting.
Now with the phone connected to you computer... Go to device manager and Uninstall any Samsung drivers that u would see in Device Manager (Windows). If you see anything like adb drivers then also Uninstall. If you have any other phone drivers (Nexus, LG etc), Uninstall those as well. Also from Control Panel>Uninstall a Program, Uninstall any USB drivers programs that u would see in the list.
Once u are certain you have Uninstalled all phone & adb USB drivers. Also Uninstall Kies completely. You might also need to disable Windows auto driver installer. Reboot ur laptop / computer.
Once computer reboots... Google for Samsung USB drivers for mobile phone. The version I used was v1.5.27. You can try with any version. Some people have had the best luck with v1.4.60. Install the drivers and reboot the system again.
Switch off ur phone. And go to download mode.
Then connect ur phone to the computer via USB cable and see what happens? Look in Device Manager again and see what is showing. Also try using a USB 2.0 port for best results.
Once done... Unplug the phone... Get out of download mode.... (u can simply put the battery out of the phone)... Or long press the power button... Let the phone restart. Plug the phone again to the computer and see what happens?

Oh and make sure USB debugging is Off when doing the above. USB debugging should always be Off... At least till ur pc detects ur phone.
Have the drivers installed on ur system before u are troubleshooting.

Android version 4.1.2
Baseband version I9300ZCLK2
I've installed samsung usb driver, kies, and even adb driver installer..
But it doesn't help me at all..
Then i go to his thread, i tried to dial *#7284#, but nothing happen..
I've put it in download mode too..
And my pc can't detect my phone..
Please help me..
Sorry for my bad english..
Please read post # 12.
These are the only things I can suggest.
If all fails then your only option would be to download "Airdroid" from Play store.
It will not solve your issue but will let you transfer files to your phone at least

Is your usb cable original Samsung that came with your 9152? If not then you should use an original cable as from experience a duplicate cable will not work with kies, but will charge your phone though.
same thing
I have the same problem. Mayby the kies not capable with windows 8?
I have tried couple versions of kies and i have the original usb cabel. Still the program can not recognize my device..
