Title: VCP driver on macOS 11
Post by: kalle on September 10, 2020, 12:20:41 PM
The current VCP driver can't be installed on macOS 11 beta 6 as Apple seems to consider it a "legacy system extension" (https://support.apple.com/en-us/HT210999). Is there any plans to provide a driver that works on macOS 11?

Hello,

We are currently working on a .dext version of the driver to be compatible with the newer versions of macOS.
 
However in macOS 10 Apple distributed a VCP driver built into the OS which works for all standard FTDI devices, this was called AppleUSBFTDI.kext pre-Catalina and AppleUSBFTDI.dext in Catalina. I haven’t had a chance to look at macOS 11 yet, but I believe the inbuilt apple driver should still be included.

I use two (2) devices with a FTDI chip. An RT Systems USB-62C cable and a Microham USB Interface III.

The RT Systems USB-62C cable works fine with the built-in .dext in macOS 11 Big Sur Beta 6. The Microham USB Interface III doesn't.

Hello,

I am unfamiliar with the Microham USB Interface III, could you share its details from the hardware monitor similar to the attached screenshot?

Hello,

I see that your device is using the Product ID (PID): 0xEEEF with our default FTDI Vendor ID (VID): 0x0403.
This VID/PID combination is included in our VCP driver (FTDIUSBSerialDriver.kext), however it is not included in the inbuilt Apple VCP driver (AppleUSBTDI.dext).

Unfortunately at this time we do not have a .dext version driver available for macOS 11 Big Sur, but we hope to have this available shortly.

Hi there, we are also looking forward to the .dext driver version.

We have a few products using the default FTDI vendor ID with our own PID (granted by FTDI some years back). Will our VID/PID combination also work in the upcoming .dext driver?

Thanks

If your VID/PID combination is currently included in our macOS VCP driver's Info.plist file then yes it will be included in the .dext version of the driver.
