  • When this situation of disassociated CAT ports occurs, there is a simple fix to remove the unassociated virtual serial ports in Device Manager. Do NOT attempt to remove the FlexRadio Virtual Serial Ports using Device Manager. This will not remove the ports and can possibly damage the registry entries associated with each port's configuration.

This section describes the class-of-device (CoD) registry subkeys and entries that apply to the Bluetooth driver stack.

'COD Major' and 'COD Type' Values

Original equipment manufacturer (OEMs) can use the COD Major and COD Type values to indicate the Class of Device for a Bluetooth-enabled Windows device. After the Bluetooth class installer sets the Class of Device based on these registry values, a remote device can determine whether it is connecting to a portable computer, a desktop computer, a phone, and so on.

The registry path to the COD Major and COD Type values is:



Note that setting these values changes the Bluetooth Class of Device for the system, regardless of which Bluetooth radio may be attached. You can set the COD Major and COD Type to DWORD values as defined for the Class of Device field values in the Bluetooth SIG Assigned Numbers.

I had my Flex-Control go bad and it shut down my computer and have seen external Hard drives and many other external USB device at work shut down the mother board due to failures, this is why I first said to unplug ALL USB devices except the Keyboard and Mouse but even one of these devices could have a issue so you may want to try a spare to. Content provided by: FlexRadio Systems Engineering The Windows executable available for download below is a diagnostic tool that can be used to verify that your FLEX-5000 / FLEX-3000 Firewire device driver is loaded properly and you computer is properly communicating with the FLEX-5000/3000 transceiver. There are two procedures documented here.

The Bluetooth profile driver, BthPort.sys, reads the COD Major and COD Type values to determine how it should respond to a device inquiry. These values affect only the COD_MAJOR_XXX and COD_XXX_MINOR_XXX bits of the Class of Device. The COD_SERVICE_XXX bits are not affected by this registry entry.

If the COD Major and COD Type values are not set or are set to invalid values, the Bluetooth class installer will set these values to COD_MAJOR_COMPUTER and COD_COMPUTER_MINOR_DESKTOP, respectively.

Scanning Parameterization Settings

Profile drivers can specify scanning parameters settings for their device(s) in their profile driver's INF file to tailor to the specific needs of a given device scenario.

You can override the default system scanning parameters by providing one or more of the following scanning parameters listed below into the AddReg directive. More information on how to use this directive can be found in INF AddReg Directive.

Value NameTypeMin ValueMax Value
HighDutyCycleScanWindowDWORD 0x100010x00040x4000. Shall be equal or smaller than the HighDutyCycleScanInterval parameter

Changes to scanning parameters make a global impact on the performance of the Bluetooth stack. Making changes to scanning parameters programmatically is not permitted. Using Low Duty Cycle scanning parameters that are too aggressive can not only have a negative impact to the available bandwidth for other Bluetooth Low Energy connections, but also for Bluetooth BR/EDR connections.
