Yesterday I wrote to Paul:
Hello, I have installed Teensyduino together with the Arduino environment. I've also switched Tools to Teensy 3.5, compiled 'blink_fast' sample and get the error msg 'No Teensy boards were found on any USB ports of your computer' when I Load.
With an 'Arduino Uno' board, Tools/Port say I'm using COM4, and there's sound when I'm attaching/detaching the Uno's USB cable.
With the Teensy 3.5, there's NO sound attaching/detaching the USB cable, Load fails as explained above and COM4 doesn't show under Tools/Port! WHY???

A few hours later I got this reply from Paul:
Quick answer:
The most common problem is due to charge-only USB cables.
Teensy sometimes uses HID protocol, especially while programming, so in
those mode no COM port is seen. But if you have Teensyduino 1.42 or
high installed, it should show in the Tools > Ports menu as HID.
Paul,
Thanks for your quick reply! I wasn't aware there are 'charge-only USB cables'! I seem to have several of those, but looking through my drawers, I found a much older cable that did make a "sound" when I attached the Teensy 3.5 with it; I can now compile and download programs. That problem solved!
BUT, now I got another problem! The same USB port in my laptop (Windows10), instead of still being COM4, it has become COM6! When I try to use the Serial i/f in my 'blink_fast' code and try to use the 'Serial Monitor', it assumes COM4 (which it can't find); I haven't found a way to change from COM4 -> COM6...
