I got a teensy 2.0 from my friend but I found it's really hard to write new firmware to it. I needs to be very lucky to 1 out 10 chances to upload the firmware successfully. It took me a week time digging out QMK source and teensy loader cli and things looks very very normal.
Tonight I find out that, my usb got connected and disconnect repeating within seconds even with a new cable. When I look at the chip, I found it's hard to tell the IC. There's no paint on it@@ I heard it was bought from Taobao...
Here comes the million dollar question... Is it a counterfeit teensy?
