Why is Windows 7 having such a hard time installing this simple driver that apparently works well on Windows Vista? If anyone has had success installing the drivers for the Prolific USB-Serial in Windows 7, please post insights. If you have a previously installed a version of these.

Download the repo and follow the instructions in the corresponding folder. This repo contains the drivers for Linux, macOS, and Windows. If you connect by USB, you can use Cura (or whatever slicing software) to communicate directly with the 3D printer rather than placing the sliced files on the SD card. To use them with the Arduino IDE or CLI, you need to install extra drivers. Yes, this would be used to connect the printer to your computer over USB, assuming that you have the same board that came by default in my machine. After selecting the appropriate path, it thinks for a minute then displays a window saying, 'Windows found driver software for your device but encountered an error while attempting to install it.' Further down in that window it says, 'USB-SERIAL CH340, Access is denied.' I also tried downloading the latest drivers from Prolific's web site (the manufacturer's of the chip inside the USB-Serial adapter), but those also failed. The CH340 and CH341 USB controllers are commonly found on 3rd party Arduinos. and browsed to the path of the downloaded drivers.

The USB2.0 to RS232 converter did come with a mini writable disk with no information.

However, when I try to install the driver, it gives the message 'Device driver software was not successfully installed.' I right-clicked on the device in Device Manager and selected Upgrade Driver. VID1A86&PID7523&REV0252 VID1A86&PID752 I am still unable to find the correct driver. I recently purchased a USB to Serial cable for my MacBook (running Windows 7 Beta 1, via Boot Camp) to control my Uniden BCD396XT scanner radio.
