A Code 9 error is generated in the "Device status" box for Bluetooth Enumerator on a Windows Vista-based computer that has a USB Bluetooth radio device installed

Consider the following scenario:
  • On a Windows Vista SP1-based computer that has a USB Bluetooth radio device installed and running, you perform a Windows Hardware Quality Lab (WHQL) Bluetooth "Disable/Enable I/O" test.
  • In this test, you use the Driver Verifier utility (Verifier.exe) to monitor the driver.
  • Then, you disable the Bluetooth Enumerator device in Device Manager.
In this scenario, a warning bubble appears on the taskbar, and it contains a warning that the device hardware ID cannot be found. Additionally, a yellow exclamation mark (!) appears next to the Bluetooth Enumerator device in Device Manager. Finally, a Code 9 error is generated in the Device status box in the Bluetooth Enumerator Properties dialog box.

Note After this issue occurs, you cannot enable the device before you restart the computer.
