You remove an external USB 2.0 hub from a Microsoft Windows XP-based computer. After you do this, USB devices or optical drives that were connected to the USB 2.0 hub are not immediately removed from Device Manager. The devices remain in Device Manager for several minutes, even though they are no longer connected to the computer.
Note This problem can also occur when you remove a Windows XP-based computer from a docking station. The problem occurs if the docking station contains an integrated USB 2.0 hub that has connected devices.
This problem may occur if an audio-enabled CD device is also connected to the USB 2.0 hub or to the docking station. The problem occurs because the Redbook.sys digital audio playback driver is waiting for a worker thread to exit. The worker thread is waiting for a resource that is held by the Plug and Play manager for the device removal.
