I hope someone can help me. I recently installed VS 2005, HP iPaq running Mobile 5.0, Activesync 4.2, and Windows Loopback Adapter.
I can create a smart device application and deploy it on the 2003 emulator, but whenever I try to deploy the app onto my pocket pc it keeps returning an error stating:
Description: "Connection to Device Failed"
File: "Device Connectivity Component"
I tried to connect to the device thru: Tools - Connect to Device - Windows CE 5.0 Device, but it returns an error stating:
"Connection failed. An invalid argument was supplied."
I tried deleting the CoreCon folder, but that didn't help. Any suggestions would be greatly appreciated, since this is relating to work.
Thanks,

Hi,
I had the similar problem, and it worked by doing following steps
0. Close your VS 2005 and any remote tools .
1. Delete the contents of CoreCon folder (Not Corecon folder itself).\Local Settings\Application Data\Microsoft\CoreCon\1.0
2. Reopen the VS 2005
3. After that you can connect the win CE device or Pocket PC by following steps from http://msdn2.microsoft.com/en-us/library/ms228708.aspx
Hope this will help. Good luck
Thanks,
