You can initiate a connection from both the computer side and the phone side (Click PC Synchronization in TouchXperience to initiate the connection from the phone). You can connect via both USB and Wi-Fi, but for the first time you have to connect via USB. This is necessary so that WP Device Manager can install TouchXperience and your phone gets the IP address of your computer.
In the current version, you cannot manually change the IP address of a computer or phone, as well as change their port.
Make sure that port 8007 is not blocked by a firewall on the computer, and also that port 8107 is available on the device.
When the WP Device Manager initiates a connection and cannot connect to the phone: in case you are connected via USB, it will launch TouchXperience on your device; otherwise, a push notification will be sent to your phone with the advice to launch TouchXperience manually.
For some tasks it is necessary that the screen of your phone is unlocked.
No need to run Zune in order to use WP Device Manager.
If WP Device Manager does not start, make sure that you have installed everything you need, and also try reinstalling .NET Framework 4.0 and developer tools.
If you are unable to connect or some features are not working or are working incorrectly, go to Settings in WP Device Manager, click Restore default settings, and then restart your computer.
If you get the message "TouchXperience version 1.2.3.0 or later is required", this means that the Device Manager cannot connect to TouchXperience. To solve this problem, go to Settings in WP Device Manager, click Restore default settings and restart your computer. Also try disabling your antivirus software or firewall.
If you have problems with the connection, also try the following: disconnect / reconnect your phone, close Zune, restart WP Device Manager, make sure your phone is determined to Zune, otherwise restart your computer.
WP Device Manager and some of its components may be recognized by your antivirus software or firewall as a potential threat, this is a false alarm, add WP Device Manager to the exceptions in your antivirus software and firewall.
WP Device Manger automatically turns off when you exit TouchXperience (for example, when you launch an application or exit the start screen). This is not a bug, it is a result of the fact that TouchXperience stops due to the lack of native multitasking in WP7. To work around this, you can enable multitasking in the TouchXperience settings.
Click on the menu title in TouchXperience (at the very top) and the main menu will appear.
If you want to take a screenshot of another application on your phone, you must enable multitasking in the TouchXperience settings.
On non-HTC devices, you only have access to \ Windows and \ My Documents and some folders will look empty. This is due to the fact that so far only HTC devices have full access to the file system.
Programs installed not through WP Device Manager are also not recognized on non-HTC devices (they are identified by their id). To solve this problem, you can simply view your xap-files, information about the programs will be automatically cached and displayed in the application manager.
Some versions of applications are displayed incorrectly. This is due to the fact that some manufacturers do not update the manifest in their applications when they release a new version. To solve this problem, you can check the application for updates, and then click Dismiss All. After that, all your applications will be updated to the latest versions.
You can not copy many DLLs and EXEs in the \ Windows folder. This is due to the fact that these are not files, but modules.
You can check the version of TouchXperience in Settings or in the list of applications in WP Device Manager.
To use WP Device Manager with Windows Device Stage, you must have Windows 7 installed and driver signature verification must be disabled, unfortunately, this is due to the fact that Windows 7 recognizes only digitally signed drivers.

Updated: If you have win7 x64 and when connecting the phone, the program causes an error - install EasyBCD_2.0.2.exe (1.31 MB)

In it, click the advanced settings, then the advanced tab and tick the box "Allow installations of unsigned drivers on 64-bit Windows" and then "save settings". Be careful, this allows the installation of unsigned drivers.
Also, if there are any problems, try installing a previous version of the program.
Updated 2.05.2011:
Added registry fix for those who have problems with the connection ("TouchXperience version 1.2.3.0 or later is required") on windows7 x64. Need to apply this file on PC -WPDeviceManagerFix.reg(306 bytes)

Also, who has problems with the connection, just connect via Wi-Fi:

1. Connect your phone to your computer via usb. Do not forget to turn on Wi-Fi
   
2. Run WPDM
   
3. After receiving the message "TouchXperience version 1.2.3.0 or later is required", touchXperience should start (if it doesn't start, do it manually)
   
4. Disconnect the phone from usb
   
5. In WPDM, click "connect"
   
6. The phone must be determined by WPDM
