Hi everyone,
i'm having difficulties to connect my sgs2 to a pc.
i have tried it on 3 different machines (win7 64, win7 64, winxp 32) with the same problem:
I works fine when i first connect the phone in download mode. But as soon as i disconnect the cable i can't connect it again. Windows sais that it doesn't recognize the device and that's it. The device manager shows an "Unknown Device" under USB-Controller. And i am not even able to install drivers by manually pointing windows to a file.
as already sais, i have tried that on 3 different machines. I have tried installing driver via kies and via the driver file that is available here in the forums. i have also tried different usb ports.
Any ideas?

EDIT: Maybe this is an important information: the phone connects fine as long as it is running (can be found via adb, logcat is working, etc...) it only makes problem when in download mode...
I had exactly the same issue yesterday on my Windows 7 box. In the end I connected the phone in normal (not download) mode. Into device manager and uninstalled the drivers through there.
Then I uninstalled Kies and reconnected the phone, I allowed Windows to search windows update to find drivers (not that it did as it couldn't find any and reverted to the local ones. Then disconnect the phone, re-install Kies, run the install drivers from the tools menu, close Kies. Run up Odin and the connect the phone in Download mode, low and behold 2 minutes later after a lengthy installation process the phone was picked up.
I tried a number of things but for some reason this specific order seemed to sort it.
Hey,
thanks for you hints. But they didn't work for me.
I found the problem: believe it or not, it was THE CABLE. I went and got another cable and this one is working fine all the time. The other one doesn't... Very strange...
Ok, this is getting annoying.
Every time I plug my phone to pc, I get "device ID was not found" message. It was like this from the very beginning.
Should I reinstall Samsung drivers, I can log into phone. But if I turn pc on and off - those drivers are forgotten, and phone is not recognized again.
I tried Kies, they do not recognize phone also.
When I reinstall drivers (from Samsung) message says I already have them installed. But the only way phone will connect is when I reinstall drivers again.
Any suggestions?
Just unplugged and replugged it again - logs in fine. But, like I said - turn pc off - those drivers are forgotten...
Hello Everybody,
I am having some issues with the drivers when trying to use flashtools on a Windows 8 64bit system. I have installed the flashtools driver with driver enforcement disabled and the drivers were all properly installed (as it claims). When I try to connect my phone in flashmode, I get a message saying USB device is not recognized however it is recognized when the phone is on.
After hours of troubleshooting and frustration, I decided to try to put my phone in flashmode immediately after I restart and I went to flashtools and miraculously it worked! This shows that my computer is able to detect the phone but only before it is booted.
Does anybody know how I can get it properly working without having to restart for every flash?
Regards,

My computer connects fine to my Z2 tablet via usb, both when in mtp-mode as well as in mass storage mode. I can browse the content the tablet via computer.
However Sony's own software, the pc companion can't find the tablet at all. There is no error message, just a complete blank when it is searching for the tablet.
I'm running Windows 7 and have tried uninstalling, reinstalling both the software and drivers but to no luck.
Anyone else with this problem or suggestion how to solve it?

I couldnt get it to work either, tried everything, even wiping the tablet.
However what worked for me was connecting the Tablet through wifi. With that I could see the tablet in PC companion, however I still cant get USB connection to work. So try Wifi?
I had the same problem. Could fix it this way:
plug in usb-cable only to your computer
start connection-progress within the software
plug in the other end of the usb-cable when prompted to connect your computer and tablet
voilà!
I never imagined, the connection-order of the usb-cable would make any difference, but it works now (whyever).
If it doesn't work for you, download, install and run the update service (http://www.sonymobile.com/global-en/tools/update-service/), follow the instructions until your computer installs new drivers (don't wipe your device and don't apply any update, just abort the progress at this point) and try again the steps above.

Tried the above and still no luck.... Does anyone have any other suggestions? The tablet is recognized as a MTP device but will not connect to PC Companion. Ironically, when I first downloaded PC Companion, it did briefly connect to the device but it looked like additional windows drivers may have installed (?). I abruptly lost connection and have not been able to get it back. Any help would be greatly appreciated. Thanks
I had same issue as u. I fixed it like this: I switched to a laptop that had windows 7 running on it instead of windows 8. Uninstalled pic companion and redownloaded from Sony site. And installed. I reset the tablet. After reset done. I ran the pc companion then I connected my tab to laptop USB. And now after 15 sec my tab was recognized and prompted for the. 402 update. That is how I fixed it.

So I picked up my Verizon LTE Xperia Z2 the other day SGP561, and am having the same issue with not being able to connect the PC Companion. Every time I try to "pair" it with my laptop (running Win 8.1) the PC Companion app tells me the pairing has failed, try again.
I've uninstalled the device from the computer, uninstalled PC Companion, factory reset the tablet, re installed the PC companion and tried again. Every time, it gives me the same error, and just will not pair.
Instructions from Sony
I just had this issue, I assume you solved it but someone else might end up here looking like I did.
These were sent from John @ Sony support for the Z2 (Works for other models too though).

Hi KapaiKiwi,
Thanks a lot for your instructions. After to navigate through the web whithout success (and reading very strange solutions) I have followed your procedure and finally I have fixed my Xperia LT15i.
I had deleted services and applications in order to optimize my phone until I reached a point where my USB connection failed. I had no way to reflash it and i felt lost.
This morning I had the plan to get a new phone. Thanks to you I have saved a lot of money!!!
