Starting in WICED Studio 6.1, the FTDI driver has been changed from using libusb0 to libusbK. When installing WICED Studio 6.1, updated drivers will be installed for WICED evaluation boards. These drivers should take effect automatically, but if they do not, follow the steps below to upgrade the new drivers. This should only affect Windows users.

 

  1. Remove the current drivers
    1. Plug in a WICED device and open the Device Manager
