FIX: You cannot use the BTHHID_IOCTL_HIDDisconnect Bluetooth input/output control to disconnect an HID device from a Windows CE 5.0-based device successfully

You cannot use the BTHHID_IOCTL_HIDDisconnect Bluetooth input/output control to disconnect a Human Interface Device (HID) device from a Windows CE 5.0-based device successfully.

This problem occurs for both of the following reasons:

• The HID profile sends a duplicate virtual cable unplug message on the control channel.
• The HID profile starts an L2CAP disconnection for the control and interrupt channels instead of waiting to disconnect from the HID device for those channels.
