Hello! I have with me a brand new Teensy 2.0 and I have been trying to use the Teensy Loader to program it. But it seems like HalfKay just does not run when I press the push button.
I have Teensy Loader 1.48 and the machine I am connecting to is running Ubuntu 18.04.4.
When I connect the Teensy to my computer, the LED starts blinking.
When I press the push button, the LED stops blinking.
But Teensy Loader doesn't do anything and still says to press the button to enter program mode.
I have the udev rules copied to the preferred location /etc/udev/rules.d/49-teensy.rules and I know these rules worked because I can still program my other Teensy.
I know it is not the USB cable not having data lines, because I have been using that same USB cable with my other Teensy.
I have tried rebooting my Linux computer and trying again--no luck.
I have tried holding down the push button while plugging in the Teensy--no luck.
I have tried connecting the Teensy to my macOS machine instead and running the Teensy loader--no luck, same problem.
On Linux I have tried these instructions https://www.pjrc.com/teensy/check_halfkay_linux.html and have verified that, when the new Teensy is plugged in and I have pressed the push button, nothing new shows up in the lsusb output (and also nothing new shows up if I $ ls /dev). I tried this with my old Teensy and I see Teensy Halfkay Bootloader in the lsusb output.
On macOS I have tried these instructions https://www.pjrc.com/teensy/check_halfkay_mac.html and have verified that "Composite device" does not show up on the profiler when the new Teensy is plugged in and I have pressed the push button. I tried this with old Teensy and "Composite device" shows up as expected.
It is as though the push button just turns the Teensy off.
I didn't buy this Teensy 2.0 directly from Adafruit but it was resold to me in the original unopened Adafruit packaging, from the same seller that sold me the old working Teensy. The LED blinks orange.
I have utterly no idea! Any help would be enormously appreciated! Happy to provide more info, I just don't know what else to add.
