After Googling various internet sites , and removing some files , I was successful in using the device with the app "Coolterm".
To do so I used the Terminal app and typed
ls -lctr /Library/Extensions/
I found .kext files for Wacom and for FTDI.
I also used the HoudahSpot app to search for files with the .kext extension.
I trashed these three :
Wacom Tablet.kext , FTDIKext.kext , FTDIUSBSerialDriver.kext
I left this file alone:
Thanks for ideas from
