Can't flash Teensy 2.0

Hi all

I found a Teensy2.0 in a drawer that I bought years ago and it's perfect for a project I had in mind. But for the life of me, I can't seem to program it with the simplest sketch.

I have tried on both a Mac and a Windows PC with a quality cable that I normally use with a keyboard. When logging Verbose Info with the Teensy Loader and connecting and subsequently hitting the Program button, I see the following:

Code:
22:35:39.280 (ports 2): purge, name=HID=16c0:0478.ff9c.1b (Teensy 2.0) Bootloader, loc=usb:120000, age=1.801 sec

22:36:00.214 (ports 2): HID remove callback

22:36:00.230 (ports 2): USB device add callback
22:36:00.232 (ports 2):   loc=120000, vid=16C0, pid=0478, ver=0001, ser=
22:36:00.232 (ports 2):   actual serailnum=0
22:36:00.232 (ports 2):   found prior teensy at this loc, age=0.019
22:36:00.232 (ports 2):     name: [no_device] (Teensy) Bootloader
22:36:00.277 (loader): HID/macos: attach callback

However, the loader doesn't seem to see the Teensy:

In Teensyduino, the device port is recognized as well. For the life of me, I can't figure out what I'm doing wrong...

One thing that does have me wondering: I read that by default the Teensy 2.0 should ship with a slow blink program (and that the led should be red?) but mine runs a fast blinking led program when plugging it in and it's a blue led.
