Ftdi Port Devices Driver



Try connecting to your machine again. If you are prompted to enter the COM port manually, enter the number from the COM Port section in the Device Manager. For example, if the machine showed up in the Device Manager under COM Port 3, enter 3 in the box and hit enter.


  • To install CDM drivers for an FTDI device under Windows 10, follow the instructions below: Connect the device to a spare USB port on your PC. 3.1 Windows Update If there is an available internet connection, Windows 10 will silently connect to the Windows Update website and install any suitable driver it finds for the device.
  • The device does not require any drivers to be loaded on the Android platform and draws no power from the Android USB port, as the device is the USB host. To support this chip, we offer a development kit and GPIO interface board to jump-start engineers' designs and provide easy access and integration into users' end systems.
  • Jun 06, 2020 I bought the adapter off Amazon- DSD Tech (China, cost $10). It has the FTDI R232RL chip and I used drivers (2.12.28) from the FTDI site. Works perfectly. So more investigating- The adapter appears as USB Serial Port (COM4) in Device Manager. The Driver information and Details under Properties are all good and the adapter works perfectly.

That sounds correct, from my experience with the Open Lighting Architecture ftdi driver you need a separate context for each port (I modified it to support a 4-port single FTDI device), so devices would definitely need their individual context.

I am trying to understand how to open and use multiple FTDI devices in the same program.
I am using ftdi_usb_find_all() to enumerate the devices and then ftdi_usb_open_dev() to open each one and identify it. Afterwards I close each device. I do this part with just one ftdi_context.
Now that I found all the devices I want to open each selected device and keep it open for reading and writing. I notice that Ftdiftdi_context contains the following:
  • libusb_device_handle
  • readbuffer
  • eeprom

All this makes me believe that I need a separate ftdi_context for each device that I want to access. Am I on the right track?

Using the ftdi_device_list that I found above I want to create a new context for each device and open it.

I tried doing

ftdi_new();
ftdi_usb_open_dev();

for each device using the old device list. But I get a SIGSEGV somewhere in the depths of usb_open() in libusb. I am thinking it is because I used a device list created with one context and now am trying to open the same device using a different context.

So how do I accomplish what I want? Any advice would be appreciated.
