Well good news. I'm not sure what happened. I ran your host test program and checked the inputs and everything looked fine. I ran the ogx360_t4 code and the USB host began functioning normally. The only hiccup is that the orange light still...

But then switched to less complicated sketches when I found it wasn't working. They utilize USBHost_t36 Appreciated. I'll give it a try

As in the first post. I am not getting any readings from the USB host data pins. The USB host is not turning on.

Yes, I was saying that fear of such a thing was the reason I didn't power it. What about feedback? I suppose as defragster said, any electronics worth a damn should have preventative measures. Yeah I suspect the TPD3S014 or TLV757P got damaged.

Is there any way to properly test which are well behaved and which are rule-breakers that put 5V where they're not supposed to?

1. I can still program different sketches to the board. 2. Yes. I've tested with a couple sketches that utilize the host port. But mostly a hex file generated by ogx360_t4 . 3. Custom cable I created from parts (female usb port connected to a...

I connected an unpowered USB 3.0 Hub to a Teensy 4.1 host and then connected a Keyboard (that I missed had RGB). This ended up damaging the host port (i'm assuming the voltage regular and/or the current switch) and I'm not getting power from...
