title: Windows won't recognize Galaxy S2 at all
body: <p>I'm having an issue with my Galaxy S2. I typically leave it in Debug mode, up until a few days ago it has worked great. I've successfully loaded APK's for testing through eclipse previously. </p>
  
  <p>I tried to load a prototype of a new app im working on and when I plugged in the S2 nothing happened, Windows didn't beep like usual and when I tried to view running devices it did not show up.</p>
  
  <p>When I look at the device manager under universal serial bus controllers, it doesn't show any 'unknown devices'</p>
  
  <p>I've tried reinstalling drivers through kies, and third party sources (as well as removing all drivers and letting windows install them again for me.</p>
  
  <p>I've tried connecting as Mass Storage Device, with debug mode on and off. </p>
  
  <p>I've restarted both my computer and phone many times.</p>
  
  <p>When my phone is off and plugged in Windows will beep and say that a device was connected but not recognized (which is more then what I get when the phone is on)</p>
  
  <p>And sometimes when I "troubleshoot connection issues" in Kies it will reinstall the drivers and after the process is complete windows will report "Drivers were not successfully installed"</p>
  
  <p>I've tried plugging it into my Windows XP laptop and it will show up as "Unrecognized device" even after I installed Kies on the laptop, and tried the driver installation it with the same results.</p>
  
  <p>Posting here is my last resort as I've spent close to 5 hours troubleshooting this issue, and searching for answers. My biggest concern is that when I do plug my phone in it will beep to say that it is charging, but windows 7 doesnt even see it!</p>
  
  <p>I appreciate all suggestions &amp; help!</p>
  
  <p>EDIT: Also I installed the <a href="http://innovator.samsungmobile.com/down/cnts/toolSDK.detail.view.do?platformId=1&amp;cntsId=9480&amp;listReturnUrl=http%3A%2F%2Finnovator.samsungmobile.com%3A80%2Fdown%2Fcnts%2FtoolSDK.list.do%3FplatformId%3D1%26indexType%3D1%26indexDirection%3D1%26sortType%3D0%26cateId%3D1025%26codeType%3DAll%26searchText%3D%26curPage%3D2%26listLines%3D%26formData%3Dnumber1%26nacode%3D&amp;nacode=" rel="nofollow">Samsung Android USB Driver for Windows</a> and windows reports that the drivers were not successfully installed</p>
  
  <p>Thanks
