I guess all of you missed the important key word 'USBXpress'!RichardM wrote:...I have now gone back into device manager and have found this, which appears to be the the serial to USB control port and this is called USBXpress which says 'Universal Serial Bus controllers' Port_#0005.Hub_#0004.
Unless the USBXpress drivers are completely removed (uninstalled), then nothing else can be done ... even if one tries to install the Silicon Laboratories 'CP210x USB to UART Bridge VCP Drivers' while leaving the USBXpress drivers installed!
If Richard is still having the problems it is probably because the USBXpress drivers are still installed and overriding any other drivers.
A user normally/usually select the USB option during the original setup of the WeatherLink software ... because the WeatherLink USB adapter (or data logger) can be connect to the computer's USB port - the instructions with the WeatherLink software are as clear as muddy waters even if Davis Instruments has been asked/requested over and over to clarify the incompatibility of the USBXpress drivers (installed by default) with any other software, other than their own WeatherLink software...
Richrad, you have to start from the beginning - you do not need to remove/uninstall the already installed WeatherLink software - but you do need to remove/uninstall the USBXpress drivers and then install the Silicon Laboratories 'CP210x USB to UART Bridge VCP Drivers'.
