MacOS ERROR "VE Direct cable: family specific matching fails"

VE.Direct cable stopped working all of a sudden on a Mac. VictronConnect no longer "sees" the device. When I plug in the cable into the mac, there is no longer /dev/tty.usbserial-VE28INOF device. The dmegs shows "VE Direct cable: family specific matching fails" multiple times.

I've tried rebooting, didn't help. Any ideas?


I must say, the device is functional, because:

1) it works when connected to my linux box

2) and

ioreg -p IOUSB

returns the following:

+-o VE Direct cable@14100000  <class AppleUSBDevice, id 0x100000cd7, registered, matched, active, busy 0 (8 ms), retain 15>

I solved this problem by removing a conflicting driver, in my case Wacom https://www.wacom.com/en-jp/support?guideTitle=How-do-I-uninstall-and-re-install-the-Wacom-driver-on-Mac-OS-for-a-Pen-Tablet%2C-Pen-Display%2C-or-Pen-Computer%3F&guideId=001-670

Judging by the number of similar issues on the net, Wacom is not the only conflicting driver.
