How do I manually install a USB driver on Windows computers?

A USB driver is a file that allows a device connected through USB such as the Open qPCR to communicate with the operating system of the computer. Some Windows computers may not automatically download the appropriate USB drivers to connect to the Open qPCR via IP To manually install the necessary USB drivers, proceed with the following steps:

  1. Connect the Open qPCR instrument to the computer with the USB cable.
  2. Open up the following link in an internet browser:
  3. From the options, download Driver Version (see image below).
  4. Open the downloaded zip file and copy all three files (“RNDIS”, “rndis”, “rndis.PNF”) into a new folder on the computer desktop. Label this folder “RNDIS”.
  5. Go to the Control Panel, then search for and open “Device Manager”.
  6. Select the “View” tab near the top of the window and select “Show Hidden Devices”.
  7. Locate “Ports (COM & LPT)” and click on the arrow. Locate the “USB Serial Device…” driver. Right click on “USB Serial Device…” and select “properties”.
  8. Select the “Driver” tab, then click the “Update Driver” button.
  9. Choose “Browse my computer for drivers” and select “Browse…”.
  10. Locate “Desktop” and click on the expand arrow.
  11. Choose “RNDIS”. Select “OK” then “Next”.
  12. The driver will be installed.
  13. You can confirm the manual driver download by clicking on “Network Adapter” in the Device Manager. You should now see “USB Ethernet/RNDIS Gadgets”.

The USB drivers are now downloaded and you can connect to the Open qPCR via direct USB connection. Open a new internet browser window, type into the address bar, and press enter. This will bring you to the login page of the Open qPCR user interface.
