Since the current computer has been upgraded to windows xp sp2, when the usb adapter is connected to the computer, windows xp will automatically install the driver that comes with sp2 for the Bluetooth adapter. In this case, the attempt to install the third-party driver will fail because the Bluetooth adapter driver included with windows has been signed. Because windows xp sp2 comes with a Bluetooth adapter driver, in the plug-and-play scheme, windows will rank it before the unsigned driver or the third-party driver, while BlueSoleil unsigned. However, the Bluetooth adapter driver that comes with windows xp cannot be uninstalled, so you can avoid the Bluetooth adapter driver that comes with windows xp by following the following steps when installing:

1. Uninstall the original Bluetooth program. Unplug the Bluetooth adapter. Restart the computer.

2. Click Start, click Run, type C:\WINDOWS\inf in the open box, and then click OK. (The path "C:\Windows" refers to the Windows XP system installation disk)

Right-click bth.inf, and then click Rename.

4. Rename bth.inf to bth.bak, and then press Enter.

5. Install third-party widcomm. When installing drivers, please choose manual installation and point the installation path to the folder where Bluetooth software is installed. (such as c: \ program files \ ivt corporation \ blue cable \ driver \ USB). If you install BlueSoleil, you can see the btcusb.inf file in this folder, so install that driver.

6. Restart the computer.

7. Install the mobile phone software and copy the cracked patch to the installation directory to run.

8. Insert the usb Bluetooth adapter. Start enjoying managing SMS and address book on your computer.
