I recently purchased a Teensy 4.1 from amazon (https://www.amazon.com/gp/product/B088JY7P2H , Seller Envistia Mall) and for the life of me I cannot get it to stop blinking and accept a program. I messaged the seller and they asked me to post here.
Here's way too much info of what all I've done up to this point.
-I'm on a Windows 11 PC
-USB cable is good, hooked up a Kindle with the same cable to the same USB port and I can navigate the Kindle folders like a USB drive
-Headers soldered onto board, but no circuits connected. It's hanging free from the USB cable at this point. I inspected my soldering, no bridges between pins.
-Arduino IDE 2.0.4 installed, Teensy Version 1.57.2 installed through the board manager
-In Arduino IDE the Teensy 4.1 board is selected and no port is listed, though under Tools, USB Type is Serial
-Picked a random example sketch that is listed to work with Teensy 4.1 and pushed it to the Teensy. Sketch compiles and I get "Upload error: Failed uploading: no upload port provided" from the Arduino IDE, but the Teensy.exe window pops up and tells me to press the button on my Teensy. The Teensy window is in AUTO mode and displays the hex file in the bottom info bar that is associated with the Arduino sketch I selected.
-Teensy has been plugged in this whole time and the red light blinks twice every 3 seconds. When I press the button, the light continues to blink the same. No change. No change in the Teensy pop up window either.
----Other notes:
-I get no noise/alert from my PC when plugging the Teensy into my computer, it does not show up in Device Manager as an HID, USB, or any other device type. Tried two cables that I confirmed worked with my Kindle. Same for both
-In the App & Browser control bit in Windows I overrode all the system settings to turn everything off for the Arduino and Teensy exe files.
-I have a laptop that I also installed the Arduino IDE and Teensy boards on and I get the exact same thing. I didn't do the App & Browser control settings, but I don't think it matters.
-Teensy has not been hooked up to anything else. Open the bag, soldered on some headers, plugged it in a breadboard and got the above. Unplugged it from the breadboard (I don't know, just in case) and still got the above.
What am I forgetting, what additional information would be useful? I expect that it is a user error keeping me from getting this to work, but I can't figure out what that error is. Any help would be appreciated.
