When I try to connect my Galaxy S2 device to my computer via USB, I get an error saying that the device has malfunctioned and is unrecognized. It appears as "Unknown device" in device manager.
I'm using Windows 7.

I tried this from my Samsung Galaxy Ace Plus and it worked: from ur mobile, click MENU > SETTINGS > APPLICATIONS > DEVELOPMENT UNTICK USB debugging, Stay Awake, Allow mock locations insert USB cable from mobile to PC/laptop > "Enable USB debugging" > OK drag down the the USB icon from the upper left part of the screen tap on "Connect USB" > "Connect to USB storage" then, automatically, ur PC/laptop will now detect ung mobile/sd device from the laptop/PC, select "Open folder to view files" there, u'll see MEMORY CARD storage and MOBILE storage as "Removable Disk..." (mine is G) YOU should now be able to transfer files from PC>mobile and vice versa Hope this helps. |

In addition to what the others have already answered, if you just want to access the files on the phone's storage and SD card, you can just mount the file system. Unplug the USB cable, then Settings > Wireless and network > USB utilities > Connect storage to PC |

Hey you can try to solve this in two ways either you can download Samsung Kies and using that you can connect your phone , or if not by that way then u can check in your phone that is your USB Debugging On its in settings Option > Application > Development see that is it checked or not, if its checked then it means its on.. You Can also Download PDA NET and install in your PC thats also one of the way if you dont want to install Samsung Kies |

I've had the same problem. I was so annoyed that I did a factory reset. It clears all your data, but it also solved my issue. |

When windows sees it as "the device has malfunctioned" it is a different issue than when it says "drivers were not installed, your device may not work properly. " If it says "malfunction" it is a problem with the usb hardware connections themselves, albeit the cable end or the device port. Try using some electrical contact cleaner and a soft tooth brush and the clear the port with a compressed air duster can. Just spray a little of the cleaner on the brush and gently clean your port and/or cable. Then spray area just enough to dry with air duster. Worked well for me. If you take it to a service shop they will do it for you for a minimal fee. |

Isn't it so strange that on some computer config it is not a problem??? In many cases a third party software is the badass ( e.g. firewall, antivirus apps.) Always try on another machine before you go back to the shop:-) |
