![]() I'm quite stuck on how to further troubleshoot or come up with a potential fix. Both options work for me, however it depends on which cord I am using. I came acrross this other way to do it also, using a different driver. You many have to re-do the above steps if you re-boot the PC or do a windows update. It's as if the 2 devices have switched identities.Ĭan I "delete" this devices from the registry somehow and start over? I've tried deleting the devices using Device Manager but when I re-connect them, they assume their old identities. Prolific USB-to-Serial Comm Port (COM) You should be able to communicate with the radio fine now. if I go to the Arduino driver folder to load the proper driver, Windows will not load as it's looking for UART drivers. I can't update the driver for either because Windows doesn't see the correct driver ie. ![]() When I connect B, Device Mgr shows it as USB Serial Device (COM4) (device A). When I connect A, the Device Mgr shows it as the UART device (device B). I have 2 additional USB devices that need to be connected: ![]() The laptop functions perfectly and Device Manager is fine. On start-up, my only connected USB devices to my laptop are a mouse/keyboard and a hub. My previous post wasn't too clear so I thought I would update with what I'm seeing. Double click on the 'PL2303 Code 10 Fix Shortcut'. The 'PL2303 Code 10 Fix' program will be installed along with a shortcut on your Windows Desktop. How can I get back to where I was, with the Arduino happy again?! Thanks, Unplug all USB-To-Serial adapters and Double click on the installer 'PL230364bitInstaller.exe'. I've tried deleting and reinstalling but the Arduino still shows up as the UART. I've tried updating the Arduino driver but Windows doesn't see it (thinks its a UART now?). Now here's the problem- whenever I plug in my Arduino, Windows thinks its the USB-UART adapter and assigns COM3 to it. Last week, I needed to install a FTDI USB-UART adapter and had problems with its drivers. I had an Arduino UNO happily connected to my COM3 port via a USB hub. If the user doesnt have a built-in serial port and didnt plug in a serial port adaptor to the USB port, they wont be able to open the port and will have an instant visual clue that the port doesnt exist.
