[Q] USB problem - Galaxy S II Q&A, Help & Troubleshooting

Yeah, so i've read plenty of topics about USB problems, but none gave me the
anserw.
I'm running Villain ROM 3.0. I just cant connect my phone to the computer (Mac).
It work well before also after flashing Villain.
What i tried:
1. connecting my phone without usb debuging ->phone gives the sound and report in the notification bar : "MTP - initializing" then "USB Connected, MTP-connected" But it does not gives a connection with my mac.
2. Connecting my phone with usb debuging ->phone gives the sound, but nothing happens. nothing in the notification bar neither on the computer. It's strange becouse before it was making the same sound and giving me the info in the notification to connect.
3. I've also tried KIES air it works fine. i can see my phone content, but when im trying to send one file (130mb) there is no reaction to this.
Also some time ago i was able to get usb working by simply choosing usb debuging and restarting phone.
But now i have no acces to my storage
Please help

I have a similar problem.
When I connect my SGSII to my PC (with USB Debugging On) I see 2 Removable Drives in Windows' Explorer. If I click on either one I get the "Please Insert Disk". If I connect to the same USB with USB Debugging off, then Kies Starts but does not connect.
Now the weird bit, if I do the same thing in the next USB port, then everything works fine.
Going back to the first USB slot then the problem reappears.
The 2 USB slots are next to each other and go back to the same controller on the motherboard. I have removed Kies and reinstalled Kies. I have uninstalled all the drivers. I have even changed the USB cable. When I plug a USB External Hard Drive into either USB, it works fine.
Maybe the phone just likes the one connection per computer. I'll have to test that out in my work's PC.
Update:
managed to get a microUSB cable and tested it on my work's PC. Exact same situation. Both PCs run Windows XPpro.
Has anyone else noticed this?

Now, when you said that, i checked with my second usb por, and everything works fine .
So thanks for your help. One working with sgs2 usb port is enought for me

Install Kies .

Turn KIES off from taskbar .
Turn USB debugging on phone connect USB mass storage mode and let windows find driver .

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 .

Yup, I did. I removed cables and turned on USB debugging, and tried the mass storage mode, upon connecting it says cable connected and to remove.
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..

PC not recognizing USB

This is a new issue, it used to work fine, but now, whenever I plug a USB cable into my phone and PC, nothing happens on the PC(No usb found sound) and the phone just shows that it is charging. I opened Device Manager and plugged the phone in and it did not refresh or find anything new. No Unknown Devices in DM either. Currently I am working with a Windows 7 x86 laptop.
Things I have tried:
-Different PC
-Different USB cable
-Factory Reset
-Uninstall/reinstalled HTC drivers
I dont know what the issue is, do I have a bad USB port? Any suggestions?
same problem

[Q] Doesn't connect to PC

Hi, I have a Galaxy Player 4.0 that I rooted with SuperOneClick. It was working fine at first then a couple of weeks ago, I noticed that my PC no longer recognizes it as a device, it just charges when I plug it in. So, I looked around andn tried a few things:
Restarted it several times
Tried with all the different modes in USB settings
Tried with different cable
Tried with two other computers, a Mac Mini and a Win7 laptop
Tried to unroot, couldn't get that to work
Did a factory data reset
Nothing works. I can't remember anything I did since rooting that would cause this, except I installed the Samsung Kies driver on the PC. I can't remember if the USB mass storage was working after Kies. Does anyone have other ideas?
Bump. This is rather a big deal, as I cannot transfer files between my PC and Galaxy player in any way other than over WiFi, which does not work reliably. I don't have a microSD card adapter either.
You might want to check if anything related to samsung/android appears in the device manager. Alternatively, to use heimdall I use Zadig to switch from samsung's driver to libusb but it does show you everything connected to your computer via usb when you check the option to list all devices. You should try this with and without usb debuging enabled. If nothing shows up you know it id your player that is at fault.

Thanks,
The first time I plugged it in without USB debugging enabled nothing showed up, when I enabled USB debugging, in Zadig and Device manager there showed up an unknown device, trying to update driver in Device manager showed that it already had the best driver, and in zadig driver replacement failed. Now, when I plug it in, either with or without USB debugging enabled, nothing shows up anywhere. I have tried with other computers and other cables, and nothing works, so I am pretty sure it's the player. I am willing to to a complete factory system reset, but I don't know how.

I'm having the same problem with my rooted 5.0. Although it's not a huge problem for me (I use dropbox for file syncing) I would love to sort this out, let me know if your factory reset works!
You can find it in the Privacy section of the settings menu.

I suspect you have a faulty usb connector on your device, but it doesn't hurt to do a factory reset. But you might want to backup your data first Did you try to jerk the usb cable in your player? A loose/broken connector would explain all your problems. Even if it is a software problem, I can't see how to flash your device with the original firmware since you don't have a sdcard & usb doesn't work...
Btw, I was referring to zadig only to show the devices attached to your computer, not to change the driver!

Thanks, I only tried to change the driver because it showed no driver already installed. I have a bit of electronics background so I may crack it open and take a look at the connector. I already tried the factory reset in the privacy menu, but that only wipes data apparently, not the system. I do have an sd card, I just don't have an adapter to the PC.
EDIT: After wiggling the cable around a bit, it showed the USB icon in the status bar, so I clicked connect USB mass storage, but the computer still showed a badly installed driver and then after some more wiggling the icon disappeared, so I am pretty sure it's a problem with the connector. BTW, how would I flash the stock firmware to unroot?

[Q] Galaxy S2 GT-I9100 won't connect to PC via USB

I'm having an issue with my Samsung Galaxy S2 GT-I9100 (running on stock Jellybean 4.1.2) no longer connecting to the PC via USB. It had been working fine up until a few days ago.
When I connect the USB cable, it only charges the phone. It doesn't show that it is connected in MTP mode and no USB options appear in the pull down notification bar. I tried locating the phone on the computer in Windows Explorer and the Device Manager, but it wasn't there at all. There also wasn't any unrecognised device in the Device Manager.
I’ve tried the following:
Using different USB cables. Tried two official Samsung cables, a Belkin charge/sync cable and a generic cable
Plugging into different USB ports on 3 different PCs/notebooks (running on Windows 7/8)
Turning on/off USB debugging mode on the phone
Going into Settings>Wireless and networks>USB utilities. After tapping "Connect storage to USB", it will prompt to connect a USB cable even though it is already plugged in.
Booting the phone in safe mode and connecting the USB cable
Installing the latest version of KIES. I had never used the software before but gave it a try. KIES wouldn't detect the phone
Uninstalling and reinstalling the latest Samsung drivers
Dialling *#7284# for the PhoneUtil options and checking it was PDA mode under the USB option.
Turning off the phone, removing then re-inserting the SIM card and battery
Cleaning the micro USB port on the phone
I have not made any changes to the phone (or PCs), so I'm not sure what has happened for the USB connection to stop working.
Your assistance would be much appreciated.
That is very weird. Are sure you didn't change the USB connection type?

Definitely sure.
I'm wondering if maybe the micro usb port is damaged, even though there's no problems charging the phone.
That is very possible, the port can be damaged in a way that only allows charging.
Hey guys, My micro-usb was damaged so i changed it with a new one... It didn't work and phone was charging instead of Mass Storage or Debugging mode !
I thought its fake and a bad quality micro-usb so i changed it again and still have the same problem.
I have the same computer, same cable and everything is same, even the programs which i installed in both phone and pc are same, but it wont connect to pc.
My moms phone can be connected with my cable.
Ok, before i change the Micro-Usb, it was fine but not charging as good as normal. I mean at least i was able to upgrade or downgrade my android version )
Can anyone help me ? I already did a factory reset and removed the SD card. No lucks ... ( i also tried other cables and other computers, but the problem is ONLY with my damn phone )
I'm running Android 4.0.3 KH3

[Q] usb connection not recognized on PC

When I tried to connect my rezound to my desktop PC the PC tells me the usb device is not recognized. It used to work where I can connect to my PC and look through files on my rezound, but it hasn't been working for a while. Does anyone know what the issue is? I tried enabling usb debugging and tried installing HTC sync and used some of the settings in "connect to my PC" section of the settings, but it still doesn't work. What I want to do is backup some files and eventually root and flash for the first time. I currently have an S5, but I want to root and flash on my Rezound. Thanks for any help.
Update: I got it work. I think it may have been a cable or port that wasn't working right as I used a different cable and usb port on my PC
