We strongly recommend troubleshooting Bluetooth connections in embedded mode first. When the Bluetooth receiver is operating in HCI mode, it requires more resources and limited options.
Bluetooth Connection Assistant (BCA) hangs during installation or when switching from embedded to HCI mode.

This is a vulnerability of Bluetooth products operating in HCI mode. In most cases this is caused when the Bluetooth stack fails to install correctly. If you are experiencing this uncommon issue, it will require a working mouse or keyboard/mouse set if your system is password protected.
Please try the suggestions below:
- 1. Switch to a different USB port connected directly to your computer, please avoid a USB hub or pass-through device.
(The Bluetooth receiver requires 400mA and a passive HUB only supplies 100 mA.) - 2. Restart the system and the BCA will continue to install the Bluetooth stack drivers.
- 3. Uninstall SetPoint and (if installed) Widcomm Software from “add / remove programs” in Control Panel. The keyboard and mouse are standard USB HID devices and they will function with native Windows USB drivers.
- 4. For advanced users: Manually install the Bluetooth stack drivers. Widcomm stack drivers "btwusb.inf" are located in “program files\Widcomm\Bluetooth software\bin”
- 5. The Bluetooth wireless connection is guaranteed when the Bluetooth receiver is in embedded mode
Troubleshooting suggestions for Bluetooth Connection issues:
- 1. Make sure the keyboard and mouse are powered to eliminate a hardware issue. Follow the embedded mode reconnect procedures to reconnect the devices.
- 2. Keyboards and mice are like microcomputers, they may require an occasional reset. Try executing the embedded mode connection procedures after a reset. (Reset the keyboard or mouse by removing the batteries or switch off/on .)
- 3. When it is verified that the hardware is a non issue, check the drivers in Windows Device Manager. There are times a driver issue can look to be a connection problem. (Drivers can also be verified by using SetPoint as a guide. if SP displays your device then drivers are ok.)
- 4. If both the keyboard and mouse are having connection issues when the Bluetooth receiver is in embedded mode, there may be an interference related issue. Interference issues can be caused by built-in Bluetooth transmitters or wireless internet router operating on the 2.4GHz range. Try using an USB extension cable to relocate the Bluetooth receiver.
