How to install the USB interface for Windows 8 or Windows 10 ?
 
When your USB Receiver has Firmware 4.0 or newer, then Windows 10 does not need any driver to be installed for the USB Receiver
If your USB Receiver has Firmware 4.0 then there is a sticker on the bottom of the USB Receiver saying "Firmware 4.0"
Windows 10 can not detect a USB Receiver with a firmware version older then 4.0.

If your USB Receiver has a firmware version older then 4.0, then you first need to update the Receiver on a computer with Windows XP, Vista or Windows 7 with working 32 bit BioSemi drivers or 64 bit BioSemi drivers installed.
After you have updated the Receiver to Firmware 4.0, it will be detected automatically on all Windows versions without any driver to be installed. (windows PnP native drivers will be installed automatically)

If you install the BioSemi drivers on a Windows 10 computer, then all USB Receivers will no longer be detected correctly, you will need to clean the registry with this tool. This tool removes the BioSemi drivers.
 
 
If you tried to connect a USB receiver with an 'old' firmware (lower then 4.0) to an operating system newer then Windows 7, then the USB receiver will not be detected correctly. In order to upgrade the receiver to firmware version 4.0, you can choose to ship the USB receiver to BioSemi, or reprogram it yourself:
Ship your USB receiver to BioSemi: - BioSemi will update the firmware to Version 4.0 and ship it back to you. (free of charge)
- Clean the registry of your new PC with the RegClean tool.
Reprogram the receiver yourself: - Connect the receiver to an old PC with XP, Vista or Windows 7.
- If needed, install the drivers (32 bit BioSemi drivers or 64 bit BioSemi drivers)
- When the Receiver is detected correctly, then update the firmware of the Receiver
- Clean the registry of your new PC with the RegClean tool.
