Windows 10, Windows 8, Windows 7 and Vista will install Windows Plug and Play (PnP) drivers for the BioSemi USB interface automatically (no drivers need to be installed). But this will only be done with USB receivers with 'firmware 4.0' or newer. (if the sticker on the bottom of your USB Receiver does not say 'Firmware 4.0' then you do not have Firmware 4.0) |
So, with USB-receivers with 'firmware 4.0' It is no longer needed to download and install the USB drivers from the BioSemi USB stick or website: Windows detects the USB-receiver when it is connected, and installs the drivers automatically. USB-receivers with the latest firmware are labeled (underside) with "firmware 4.0" (receivers delivered after February 2016). If there is no firmware version shown at the underside sticker, then the firmware of the Receiver will be older than 4.0 and the Receiver will not be PnP))
Older USB-receivers will still need the driver to be installed. If your USB Receiver is working correctly, then there is no need to upgrade the firmware. But if you want to upgrade the firmware, then you can do this with the below Firmware update tool. See the boxed text below how to reprogram the USB receiver and/or clean the registry. |
PS: The Firmware upgrade tool ONLY works on computers where the USB Receiver is detected correctly, with a working, new driver installed: MS WinUSB2 (see below) |
ally before a USB-receiver with 4.0 firmware will be able to reinstall the drivers) |
 |
If a USB-receiver with an older (before 4.0) firmware is connected to a Windows 10 computer then the Windows 10 driver will stop working and will have to be uninstalled. See the boxed text below how to clean the registry and reprogram the USB receiver. |

Receivers with Firmware 4.0 do not need any drivers to be installed (PnP: Plug and Play). But, when the old driver (driver name: BioSemi USB) is still installed, then the Receiver will not be able to install its own PnP driver. So, always first remove the old driver.
On (new) operating systems with no drivers installed, a Receiver with Firmware 4.0 will automatically install the Windows P&P driver (MS WinUSB2 Driver) |
