Straight to the point as I need this fixed ASAP.
My phone can charge via mains and USB port on my laptop.
I cannot however mount SD Card or go into USB Debugging mode. The menu on the phone does not show up at all. Only charges.
I have tried different cables including official sony ones and a few third party ones to no avail.
I tried different PC's still nothing.
On the occasion I get "USB device not recognised" but it isn't a driver fault at windows end.
Done a factory reset of the phone... still nothing.
Please help

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 .

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..

whats your phone kernel? and are u able to connect to pc as usb storage? or did u flash anything weird before?
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

i tried both usb modes and reinstall usb drivers, still doesnt help!
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
