I received my first Teensy 4.1 today. I always verify the "factory" Blink appears to be working for each new board and then program a different blink rate to verify that download works. When attempting to select the port in Teensyduino 1.8.12 it shows this:

[no_device] Bootloader (Teensy 4.1)
I tried this several times, disconnecting and reconnecting the USB cable. I then verified that the Teensy 3.6 I am currently using works, and then tried the one Teensy 4.0 that I have. It also works.

Is there a chance that the "15 second" reset might fix this? I wanted to inquire before trying it.

Can I provide any other information?
