what if there is no "prolific usb to serial...." option?

it would be nice to solve the driver issue "for each connect" every time

These haven't worked for me... I'm trying to connect a HOBO microstation (H21-002) to my PC with a Startech USB to RS232 Serial Adapter cable. For some reason the HOBOware software doesn't detect the device when connected. I've updated my drivers and tried a few different others than the latest version (supposedly drivers that are adapted to the Startech connector). If comeone has ever run into a similar problem (I know it's very specific), I would love some tips or solution ideas, thanks!

Hi there, thank you for your question! First, check the cable and connections to ensure they are secure and undamaged. Next, verify that you have the correct and up-to-date drivers installed for the Startech adapter by visiting their website. You can also attempt connecting the microstation to a different PC to determine if the issue is with your current setup. If the problem persists, consider using alternative software like PuTTY or Tera Term for serial communication or contacting the technical support teams of the device manufacturer or Startech for further assistance tailored to your specific hardware setup.

Usb to serial controller driver for arm64 on Windows 11 pro on Macbook M3 can't find it anywhere. Help? I'm using Vmware fusion virtual machine.

[@RecoveritDataRecoverySoftware]

Hi there, thank you for your question! If you're using an FTDI chipset, download ARM64-compatible drivers from FTDI's website. For Prolific chipsets, visit Prolific's site for drivers, though ARM64 support may be limited. If you're using a CP210x USB to serial bridge, Silicon Labs offers drivers on their site. Additionally, try installing standard x64 drivers using compatibility mode, or check for driver updates through Windows Update.

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, Peter Osborne Australia
