Artisan is setting the TC type in the attach handler as intended. It uses the information the user configured in the Phdigets tab of the Device Assignment dialog.

On running HelloWorld.py on the driver/lib v22 I receive the same
on my MB12" running on OS X 10.12.5 Sierra. Seems to be caused by the getDeviceSerialNumber() called on the manager object that might not be fully initialised. Any update on this?
