T3.5 uploads work better using non-teensy port?

Well-known member
Using T3.5 I get the usual message at upload if I forget to select the equivalent teensy port:
Code:
Teensy should be selected from "teensy ports" rather
than "Serial ports" in Arduino's Tools > Port menu

If I don't follow the advice the sketch uploads and starts auto-magically (no button push) ... !?

If I select the equiv. teensy port and upload I get message below and I have to push the button

Code:
Unable to open COM19 for reboot request
  Windows Error Info: Access is denied.

Teensy did not respond to a USB-based request to enter program mode.
Please press the PROGRAM MODE BUTTON on your Teensy to upload your sketch.

Unless I am missing something I'm inclined to ignore the message, use the ordinary port and save time?

In case it's important: in both cases the T3.5 target is running a sketch and outputing occasional text to Serial (e.g. the Wire/I2C scanner) when the upload is started.
