Here are the latest step by step instructions for installing a USB to serial cable plus identifying and changing your com port number. This works with all Windows operating systems.
The following procedure works with all of our cables including the Allen Bradley 1747-UIC, 1761-CBL-PM02, 1747-CP3, and 2711-NC13
1. To begin, click the start menu and type 'Device Manager' and click the Device Manager link.
Expand Universal Serial Bus controllers by clicking the arrow to the left of it. Right-click the first USB Root Hub device and select Properties. Click the Power Management tab. Clear the box next to Allow the computer to turn off this device to save power. Click OK to apply the setting. Microsoft-provided drivers for USB-IF approved device classes. For composite devices, use USB Generic Parent Driver (Usbccgp.sys) that creates physical device objects (PDOs) for each function. For non-composite devices or a function of a composite device, use WinUSB (Winusb.sys). You're right but you'll find other kinds of Universal Serial Bus (USB) devices out there. These non-standardized USB devices require hardware vendors to write native drivers and SDKs in order for you (the developer) to take advantage of them. Sadly this native code has historically prevented these devices from being used by the Web. On Windows, even if the serial driver installer has run correctly, sometimes Windows will retain old information in its registry and fail to load the driver. The Device Manager will show 'USB Serial' with an error, instead of 'USB Serial (Communication Class, Abstract Control. Without your USB to serial adapter plugged in, your Device Manager should look something like below. Plug your USB to serial cable into your PC's USB port. Chances are the drivers are already installed. Look for it to show up under 'Ports (COM & LPT)'.

3. Plug your USB to serial cable into your PC's USB port. Chances are the drivers are already installed. Look for it to show up under 'Ports (COM & LPT)'. If it does, then note the COM number at the end of the description and proceed to the software you are using it in. If it doesn't show up under 'Ports (COM & LPT)' then proceed to step 4.
4. If your cable does not show up under 'Ports (COM & LPT)' of the Device Manager then you need to install the drivers. They can be found in the PLC Cable Drivers section of our Drivers, Software, and Manuals page. Download them and extract the zip file to your PC.
5. Navigate to the 'Drivers for manual installation' folder and you will find two folders named CH340 and CP210.
6. Double click on the CH340 folder and you will find an EXE file in it. Right click it and select 'Run as Administrator'. Note that this will not work by double clicking the EXE file.
7. Now navigate to the CP210 folder and then to the CP210x_VCP_Windows folder. You will see two EXE files, one for 32 bit and one for 64 bit. Right click the one that matches the processor of your PC and Right click it and select 'Run as Administrator'. Note that this will not work by double clicking the EXE file.
USB communications device class (or USB CDC class) is a composite Universal Serial Busdevice class.
The communications device class is used for computer networking devices akin to a network card, providing an interface for transmitting Ethernet or ATM frames onto some physical media. It is also used for modems, ISDN, fax machines, and telephony applications for performing regular voice calls.
Microsoft Windows versions prior to Windows Vista do not work with the networking parts of the USB CDC, instead using Microsoft's own derivative named Microsoft RNDIS, a serialized version of the Microsoft NDIS (Network Driver Interface Specification). With a vendor-supplied INF file, Windows Vista works with USB CDC and USB WMCDC devices.[1]
This class can be used for industrial equipment such as CNC machinery to allow upgrading from older RS-232 serial controllers and robotics, since they can keep software compatibility. The device attaches to an RS-232 communications line and the operating system on the USB side makes the USB device appear as a traditional RS-232 port. Chip manufacturers such as Prolific Technology, FTDI, Microchip, and Atmel provide facilities for developing USB RS-232 devices.
Devices of this class are also implemented in embedded systems such as mobile phones so that a phone may be used as a modem, fax or network port. The data interfaces are generally used to perform bulk data transfer.
