Windows didn’t find a driver for my device
There are several possible causes of this problem.
1. The VID and PID of your device are not in the btwusb.inf file. Have a look at the VID and PID list page for more information.
2. You have a “Microsoft Driver” Infection. Have a read of the Manual Driver Installation page
3. Your device is faulty. Try the original driver that came with the device. If that fails then you need a new piece of hardware.
4. You are not using a USB dongle. I’m not quite sure yet how these work, there may be issues. Get in touch with me.
I can’t customise the buttons on my Wireless IntelliMouse Explorer for Bluetooth
See the Microsoft Input section of the Driver Installation page.
I get the error “There was a problem installing this hardware. An error occurred during the installation of this device. The required section was not found in the inf”
If you are connected to the Internet, Windows will sometimes try to update your driver from WindowsUpdate online. Make sure you are disconnected from the ‘net and try again. You may need to do a manual driver installation.
I get the error “There was a problem installing this hardware. An error occurred during the installation of this device. The system cannot find the file specified”
Try disconnecting from the Internet (as detailed above). You may need to do a manual driver installation.
My Nokia phone wont connect or keeps disconnecting
You may not have new enough firmware. This is a particularly common problem with the Nokia 6310i. You need to read the Nokia firmware information page. If your software is trying to connect on “COM0” you need to change the settings (see question: The driver installation works correctly, but when I try to use the serial port service it tries to connect on “COM0” and fails)
I am using a bluetooth keyboard and I keep getting a pop up when I press the capslock key or the numlock key
Download and run the Key Indication registry fragment from the Downloads page
My device appears to have a VID and PID of 0000 0000
Replace your device. It’s broken.
I get the error “Your bluetooth software license does not include use with this Bluetooth device. ”
The file patcher didn’t patch the 3 files correctly. Rerun it in safe mode.
My iPaq drops the connection to my PC regularly
I don’t have a solution to this yet. I think it is a problem with the iPaq software / firmware. If anyone knows of a solution please get in touch with me.
The driver installation is asking for a licence.dat
Either your download and extraction of the drivers was corrupted, or you have not run the .reg file included with the patched files prior to running the main setup. You can try pointing the request to “C:\Drivers\Win\Bdcact” (where you extracted the IBM drivers), but it is probably better to start the guide again from the beginning.
I am using bluetooth to connect my PC to my mobile phone so that I can use my phone to access the Internet. Internet access seems very slow
First generation Bluetooth supports 1Mbit connections which is twice as fast as most broadband Internet connections. Second generation Bluetooth devices should work at up to 2Mbits. The problem is with the mobile phone, not Bluetooth. Many phones only support 9.6.KBit. Most will not work faster than 28.8KBit. You’ll have to wait for 3G networks for fast Internet access through your mobile.
Eveything works but I get an icon in the system tray that says “Bluetooth Network — A Network Cable Is Unplugged”
This is normal. The bluetooth drivers install support for networking. If the icon bothers you then open the “Network Connections” folder and disable the “Bluetooth Network” connection.
My Dial-up and Fax Services don’t work after I have installed Bluetooth on Windows 2000 / XP / 2003 system
You need to uninstall and reinstall the Fax and Dial-Up services. This can be done in add/remove programs/windows components, BUT by default many of the windows components are hidden, including the Fax and DUN services. To show ALL of the windows components that can be selected you need to carry out the following procedure:
- Open notepad or a similar text editor
- Open the file C:\Windows\inf\sysoc.inf
- Do a search and replace, and replace ‚hide, with „
- Save sysoc.inf
Please note: Some of the components take a long time to “untick” after you click on them. When you deselect the components you wish to reinstall you will have to wait 10–15 seconds and then move the scrollbar at the right hand side, and the tick should disappear.
My Sony-Ericsson R520m keeps disabling Bluetooth
I believe this is a problem with the R520m, which will hopefully be fixed with new firmware. I recommend contacting Sony-Ericsson if you experience this problem. Until a firmware update becomes available you can try switching the phone off and back on, or using the “Master Reset” option.
I am trying to use a Compaq Multiport with a Microsoft Mouse and the response time is very slow
This is a firmware issue. Compaq don’t currently supply updated firmware, but it can be resolved by flashing the Multiport with the firmware update from TDK for their USB BT adapter
The driver installation works correctly, but when I try to use the serial port service it tries to connect on “COM0” and fails
Right click on the system tray icon and select open the configuration options. Under the local services tab click on “Add Serial Device” and follow the steps to add a new device. Under the “Client Applications” tab click on “Add COM Port” and follow the steps. The names you use for the services do not matter. Use this port instead of the default port.
I have a networking device that will not accept secure connections (there are some Bluetooth routers with this problem)
Download and run the Network Security registry fragment from the Downloads page
I’m having problems getting my D-Link DBT-120 to install
There are known firmware issues with the D-Link dongles. Download an updated firmware from the Downloads page and use the Firmware update program included with the Widcomm drivers to update your dongle.
I get the following error: “no local bluetooth device detected”
You must manually check that ALL of the following drivers have been updated the the version that you have installed. Check the following devices in device manager: the bluetooth device itself, all bluetooth com ports (there are usually 2 of these), bluetooth network “card”, Bluetooth Audio
The Mrouter software does not see any Known or Unknown devices and refresh has no effect
If you have an internal modem that is using a COM port, use device manager to disable it, try using mrouter again, and once it has come to life, re-enable the modem
