I have a FTDI FT232R device and am currently trying to figure out whether to use VCP or D2XX. I've read a little about the pros and cons of both, but am still unable to determine which one to use for this project. Since I am going to use Linux for this project, is it even worth the extra effort to use D2XX? Any kind of help or information would be appreciated.
Greetings,Sparkas

Here what I understood from some reading and experience. This list is not exhaustive and I hope that I will be able to improve it with the community answers.
Pros:
- Built-in inside the Linux kernel
Cons:
- Slower than D2XX? I've being using an FTDI device and its documentation said that there where not using the VCP method because the driver was too slow.
Pros:
- More features: For instance one could use the
FT_ListDevices()
function to get the list of FTDI enabled devices. This function is not available using VCP.
Cons:
- You have to embed the FTDI library inside the project
VCP: Is the virtual com port which appear as the legacy comm port port like /dev/ttyUSB0.D2XX interface is the proprietary interface for the FTDI devices.D2XX gives much more access to the hardware which are not available by the VCP.Like working in different mode . Asynchronous , synchronous mode or bit bang mode or writing to the eeprom chip.

PLEASE NOTE - When updating drivers, refer to the following document: AN_107 - Advanced Driver Options
New drivers are now available to support the FT4222H - for D2XX drivers please click here.
Drivers are available which allow FTDI devices to work with the following operating systems:Windows Certified | Others | Legacy |
Windows 10 (32/64) | Linux | Windows Vista (32/64) |
Windows 8.1 (32/64) | MAC OSX | Windows XP (32/64) |
Windows 8 (32/64) | Windows CE (Version 4.2 and greater) | Windows 2000 |
Windows 7 (32/64) | Windows RT | Windows ME |
Windows Server 2016 | Android | Windows 98 |
Windows Server 2012 R2 x64 | MAC OS9 | |
Windows Server 2008 R2 x64 | MAC OS8 |
Support for WinCE
FTDI drivers are available for Windows CE 4.2-5.2, 6.0/7.0 and 2013.
Support for older versions of Windows Desktop
NOTE: Microsoft have ended support for certifying XP and VISTA through their WHCK test program. From revision 2.12.24 with Device Guard Support, the driver will not load on XP or VISTA.
Differences in Driver API
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 (VCPor 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.
If a VCP driver is required for Android please refer to the following application note: TN 132 Adding FTDI Devices VCP Driver Support to Android
D3XX
D3XX drivers are only suitable for FTDI's Superspeed USB bridge services (e.g. FT60x series).
