Hello,
I've been playing around with a sketch using my mac, and everything has been working just fine. However, I needed to move the Teensy to another room to connect it to some hardware and figured I would just use a Pi to upload sketch changes to the Teensy 4.1.
So I installed the 32 bit version of Raspberry Pi OS, did a sudo apt-get update / upgrade, then I installed Arduino IDE 1.8.19 from their website and made sure it worked. Then I followed the directions on this site to install the Teensy support using the 32 bit ARM version and as far as the software goes, everything seems to be working fine. The IDE runs and when I check a sketch, the Teensy uploader fires off and is running.
My problem is that I cannot see any serial ports under /dev for the Teensy and none show up in the IDE (except for /dev/ttyAMA0 - but that port is there even when the Teensy is not plugged in).
The USB cable is a proper 4 conductor cable that I was using on my Mac to program the Teensy, I just moved it over to the Pi when I moved the hardware.
The power supply for the Pi is an aftermarket (but very popular and supported) power supply designed for the Pi 4.
Under Tools, USB Type is just 'Serial' and there is an active sketch running on the Teensy.
Any ideas why the USB port might not be showing up on the Pi?
Edit: executing lsusb only shows this when the Pi is connected:
