@n0uk

I changed the PID with FTDI's FT_Prog software on a Windows computer. It's a pretty easy exercise.

Thanks for the information. I changed the PID of the microHAM USB Interface III to 0x6001 (24577) and it works now with the standard macOS Big Sur .dext

I've doubled checked the above Product ID in the info.plist file and it looks like there are no special settings being used for this device. As such programming the device to use its Default product ID would all you to use it with the inbuilt Apple VCP driver. Are you aware of which FTDI product this device uses?

Are you sure? I received the following comment from microHAM:

Herwig,

Yes, you can change PID using tools FTDI provides, but than interfaces will not work with our Windows Router software anymore and it will be violation of FTDI rules and warranty for interface. I recommend you to wait until FTDI releases driver for Big Sur.

Apple is causing issue by creating own driver for default chip PID and breaking devices usability for manufacturers who play by rules, hope FTDI will backup their customers quickly.
 
Default chip PID is reserved only for experimenting, small batch or for certified FTDI OEM partner. Neither Anytone, RT System or Kenwood is FTDI official OEM partner. Using default PID in non OEM commercial product is violation of rules. Only owner of VID (FTDI) can assign PID to particular manufacturer/product or product range. Same VID/PID cannot be used by different manufacturers on different devices for different functionality, that's basic rule set by USB-IF authority (usb.org) and that's the reason why we have asked FTDI for assigning range of custom PIDs and using them for many years.

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.
