Hi,
I've just received my first Teensy 4.1.
I have Win11 and Arduino IDE 2.3.2.
I've added it to the preferences:

and installed Teensy:

and I can see all teensy borads when I'm selecting one:

the problem is that my PC simply doesnt connect to the device and I cant select it:

I tried to change cables (multiple times) and change USB slot but nothing happens.
When I try to connect Arduino uno - it connects fine.

Any idea what I did wrong?
thanks,
Alon.
 
The Teensy may be in a state with USB not present or not functioning when connected.

Press the Program button on the Teensy and see if that changes anything
 
after I press the button, a Red led is blinking next to the USB port on the Teensy.
Then, I started to download the 'blink' example, and this is what I got:

It looks like it is not connected to the Teensy... right?
 
That console note suggest what might be the best solution.

Under TOOLS find PORTS and select the correct item under 'teensy ports'

The red LED blinks in several ways. If you are seeing a slow steady blink (on time same as off time) repeating continuously (no pattern of blinks separated by a longer time with the LED off), this means your Teensy went into bootloader mode but absolutely no USB communication has been heard from your PC.

That slow blink almost always means you have a power-only cable. They're incredibly common, left over from all sorts of cheap products that use a USB connector for power or battery charging.

you were right :) I tried several cables, both were power only :) tried another one and it worked :)
 
Recommend testing every USB cable you get whether it has data and if not marking it conspicuously...
