    I tried the older driver available here:

Solved  PL2303 issues (Prolific USB to Serial Drivers) Windows 11 for communications with the CELESTRON NEXSTAR+ & STARSENSE HAND CONTROLLERS.

 

I had similar problems with PL2303 issues (Prolific USB to Serial Drivers) Windows 11 for communicating with the CELESTRON NEXSTAR+ & STARSENSE HAND CONTROLLERS.  Standard USB-A PORTS on computers did not recognize the drivers and were unable to establish a connection using for connecting the USB-A to USB-B Mini Lead to the HAND CONTROLLERS.

 

The PL2303 v408 Driver for Windows 11 problem was immediately solved when I attached a USB-C Adaptor with USB-A Ports to the same computer and connection of the same lead to the CELESTRON NEXSTAR+ & STARSENSE HAND CONTROLLERS.   The USB-C Adaptor & USB-A Ports were immediately recognized by the Drivers and allowed perfect communication.

 

Kind Regards,
