i try to use the bottom usb c to update firmware but fail.

Change Default USB Mode in developer options to something other than No Data Transfer. You may be missing Qualcomm HSUSB and Android adb/fastboot drivers if you are using Windows.

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
bump
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
Hello guys. I encountered with a very annoying problem. When phone is connected to pc it does not show any signs that is connected. Phone only shows that it is charging... In connect to pc settings I selected disc drive point, also I turn on USB debugging, and nothing has changed.. My computer has latest usb controllers drivers. Please anyone help me. I am verry sorry about my english.
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?

Click to collapse
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
Hello,
My phone is turned off and when I connect it with my laptop (same with my PC) it keeps getting disconnected and reconnected. My phone is ZTE Blade Q Maxi.
First, I thought that the problem was my USB cable or USB slot, but in the end, they're okay. The drivers I have installed on my laptop are following: Android ADB interface, DA USB VCOM Port, Gadget Serial (there's probably more, but they're seperated in categories). I noticed when I connect my phone, 1 driver appears - Preloader USB VCom port, about 2 seconds becauses instantly it gets disconnected.
Currently, my phone is bricked, but I've had this issue before.
Any help would be highly appreciated.
Thanks in advance!
