However, the board cannot be accessed on the Arduino IDE. We have had a few reports on Windows 10 where the driver will automatically install and the board will show up under a new COM port as USB-Serial CH340, but with a different device name.

Have use a lot of different brands of USB-Serial-Adapters and some just don't work for certain things.Troubleshooting COM Port is Not Showing Up as CH340 Windows I would lean more towards #1 or #2 being the problem. I would uninstall the old driver first, reboot, then try this one. It would install and look fine, but would get consistent output to the serial device. I have had problems when the right driver was not installed.

Try This Driver as it looks like the adapter is based on the Prolific chipset, which a lot of USB-Serial-Adapters use.

USB-Serial-Adapters internals are much faster with data than a normal serial port, and I've seen on occasion where turning those values down can help alleviate problems.

After you check/change the settings in device manager for the com port, on the "Port Settings" tab, go to "Advanced" and turn the "Receive Buffer" and "Transmit Buffer" down to the low setting.

Not knowing what scales you have, it's hard to know. Some serial scales when viewing from a terminal window, require a command entered for them to return the weight.What brand of scales are these? Have you talked to the manufacturer to make sure those com port settings are indeed correct? Device Manager-Ports(Com & LPT)-Properties of your Com Port-Port Settings tab Have you checked the Com port settings in device manager? The adapter probably installed at a default settings of 9600/n/8/1, where you need 2400/E/7/2 (2400 baud rate, even parity, 7 data bits, 2 stop bits) The adapter in device manager should read 2400/E/7/2 as well. See if you can find a computer with a real serial port, and check the scales there. Try the same adapter on another computer maybe a different OS if you can. Some of those adapters the drivers/chip-set can be weird and not allow some types of devices to work correctly. Have you used that USB-Serial-Adapter on other computers with no problems.
