Firmware

FreeRTOS based firmware on custom board using NXP imx RT1176. Using TinyUSB 0.20.0.

What happened ?

ESD test causes attached USB hub reset which causes breakdown of USB touch. This happens due to reconnect issues with USB Hub.

I've already preapared a fix using copilot and sucessfully tested it on my hardware. The patch file for the fix is attached. The patch changes files src/portable/ehci/ehci.c and src/host/hub.c,

0001-fix-from-copilot.patch

How to reproduce ?

On our hardware it is sufficient to trigger USB Hub reset by pulling reset line low for some ms.

I did some poking around and it appears the OTG descriptor preceding the interface is what makes this puke. I added a skip if it's an OTG descriptor next and the device mounts and I'm getting data.
