When you troubleshoot issues with a serial device, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:
You can check multiple ports at the same time by opening multiple sessions, putting the loopback adapter on one port, and trying to type into each session. When you can see what you are typing, you know that the COM port is working and you can see which port number the physical serial port is. Close the window for the port that you just tested to speed up the testing of the remaining serial ports.
For most of these operating systems two types of driver are available: Virtual COM Port (VCP) drivers and direct (D2XX) drivers. The VCP driver emulates a standard PC serial port such that the USB device may be communicated with as a standard RS232 device. The D2XX driver allows direct access to a USB device via a DLL interface.
To locate the drivers you want to install for a device, select which of the driver types you wish to use (VCP or D2XX) and then locate the appropriate operating systems. With the exception of Windows 98 and Windows ME, all devices are supported in each driver package.
The USB to Serial RS-232 Adapter provides one RS-232 Serial (DB-9 male) connector via one standard USB port at a data transfer rate of up to 230Kbps. You can instantly enjoy connectivity with modem, PDA, POS, or other serial devices on your PC or Mac without the hassle of opening your computer case. It provides a quick, simple, and cost-effective solution and is ideal for various communication and automation applications. This makes the USB interface transparent to serial peripherals, allowing them to easily interface with USB computers and eliminates the setup hassle found with traditional serial port connections. This device also supports energy saving suspend and resume operations.
The CP210x USB to UART Bridge Virtual COM Port (VCP) drivers are required for device operation as a Virtual COM Port to facilitate host communication with CP210x products. These devices can also interface to a host using the direct access driver.
The CP210x Manufacturing DLL and Runtime DLL have been updated and must be used with v 6.0 and later of the CP210x Windows VCP Driver. Application Note Software downloads affected are AN144SW.zip, AN205SW.zip and AN223SW.zip. If you are using a 5.x driver and need support you can download Legacy OS Software.
The most common reason that a device such as a PDA, GPS, cell phone, etc. would not work with a USB to Serial adapter when everything appears to have installed fine is that some devices will only scan a limited number of COM ports.
For instance, it is very common for a PDA to have a limitation of scanning the first four (or sometimes two) COM ports. If the adapter is installed on COM5, a device with such a limitation will not work until the COM port is reassigned to COM1 - COM4.
If you trying to install a USB device class driver included in Windows, you do not need to download the driver. They are installed automatically. If they are not installed automatically, contact the device manufacturer. For the list of USB device class driver included in Windows, see USB device class drivers included in Windows.
Starting in Windows 10, Usbser.inf was added to the %Systemroot%\INF directory, which loads Usbser.sys as the functional device object (FDO) in the device stack. If your device belongs to the communications and CDC control device class, Usbser.sys is loaded automatically. You do not need to write your own INF to reference the driver. The driver is loaded based on a compatible ID match similar to other USB device class drivers included in Windows.
Microsoft encourages you to use in-box drivers whenever possible. On mobile editions of Windows, such as Windows 10 Mobile, only drivers that are part of the operating system are loaded. Unlike desktop editions, it is not possible to load a driver through an external driver package. With the new in-box INF, Usbser.sys is automatically loaded if a USB-to-serial device is detected on the mobile device.
In Windows 8.1 and earlier versions of the operating system, Usbser.sys is not automatically loaded when a USB-to-serial device is attached to a computer. To load the driver, you need to write an INF that references the modem INF (mdmcpq.inf) by using the Include directive. The directive is required for instantiating the service, copying inbox binaries, and registering a device interface GUID that applications require to find the device and talk to it. That INF specifies "Usbser" as a lower filter driver in a device stack.
Starting in Windows 10, Usbser.sys supports USB Selective Suspend. It allows the attached USB-to-serial device to enter a low power state when not in use, while the system remains in the S0 state. When communication with the device resumes, the device can leave the suspend state and resume the working state. The feature is disabled by default and can be enabled and configured by setting the IdleUsbSelectiveSuspendPolicy entry under this registry key:
Starting in Windows 10, a Windows app can send requests to Usbser.sys by using the Windows.Devices.SerialCommunication namespace. It defines Windows Runtime classes that can use to communicate with a USB CDC device through a serial port or some abstraction of a serial port. The classes provide functionality to discover such serial device, read and write data, and control serial-specific properties for flow control, such as setting baud rate, signal states.
It should work if it has a FTDI chipset, and will probably work if it has a Prolific chipset. Some other chipsets like the CH340 are more problematic. We would not be able to provide technical support for diagnosing problems that appear to be caused by the Insignia adapter if any arise; you would need to contact Insignia's technical support if you run into driver issues or similar problems.
Looking for a way to connect a serial device to the USB port on your PC, or Mac? Vantec USB to Serial Adapter provides a simple and reliable solution. It allows you to use bridge / connectivity between the Universal Serial Bus (USB) and Serial Port Interface.

2. First, disconnect the blue Cisco USB console cable. Reinstall the Cisco USB console drive using setup(x64).exe from the Windows_64 folder which was extracted from file Cisco_usbconsole_driver_3_1.zip.
I will be moving from PC to Mac, but will need to run a Windows application that uses a serial port, using boot camp. Would I be right in thinking I would need to install this adapter under Windows using a Windows driver?
Loaded it all up fine, however my main purpose was that so I can telnet to devices on the serial port.My question is running the telnet what would I put after the telnet command to identify the port,
Prolific seem to be deliberately isolating compatibility against these devices in the newest Windows drivers, and wondered if thats the same with the mac drivers. Its just not worth wasting time putting in drivers to have to fight them out again when prolific deliberately make them to not work.
Fazed, I would l look baud rate you are using for your device. I just had a similar issue connecting to an APC UPS management interface. if you are using screen try this command: screen /dev/cu.usbserial (Baud Rate). The baud rate is standard 9600 but you can change it by typing in the baud rate you wanna use i.e. 2400.
After following these directions, and the install of the PL2303_1.4.0 appearing to be successful, I do not see the USB serial monitor option anywhere. Whether I look on system preferences under network or in terminal.
If you are not seeing the expected output from these commands, please verify that your adapter matches the 3rd photo in our post, showing the entry in system profile: -content/uploads/2011/06/03.png
I followed the instructions, and got the driver to show in system report, but never in the network control panel. ZTerm worked, showing me that the driver works (and helped as a step), but minicom is the best app for the job- easy to configure, and remotely accessible with terminal. Great site- thanks for the help!
I am using a mac. Wine is a Windows port making it possible to run Windows applications on Mac or Linux. It can use the Mac Hardware such as the adapter and forward it to the Windows application. Nonetheless i found my answer already but thanks anyway
The Problem is OSX10.11 does not allow unsigned kext to be loaded except for a workaround i described to andrius (either its the post down or up to this one) The driver itself is fine and i am using it on 10.11. The problem is the unsigned state. What you guys would have to do to make it work again is to sign the KEXT with apple and provide it in a signed state. Thats all. 2ff7e9595c
