Then clicking the Tools > Ports menu should show it as a HID device in the upper Teensy Ports part, and nothing in the Serial Ports (because HID isn't serial). If you get to that point, you can be sure your Teensy 4.0 is programed to talk RawHID. When it's done, you'll see the orange LED blinking again.

You'll know it's erasing because the red LED turns on bright for about a minute while it slowly wipes the flash chip. It will only do the erase if you release at that moment. You'll see the red LED flash briefly when you're at the moment to release the button. Teensy 4.0 has a feature to completely wipe the flash memory and write a known-good RawHID LED blink program. A less common problem is low quality cables which work with 12 Mbit speed (used on almost all Arduino boards) but not 480 Mbit speed used on Teensy 4.0. The charge-only cables sold with so many products using a USB connector for power are the most common issue. Then you can upload that verbose info file.īut for a blind guess, I can tell you the most common problem we see over and over on this forum is bad USB cables.
