/* This sketch demonstrates WebUSB as web serial with browser with WebUSB support (e.g Chrome).

• After enumerated successfully, Browser will pop-up notification

• • Click "Connect" and select device, When connected the on-board LED will litted up.
• • Any charters received from either webusb/Serial will be echo back to webusb and Serial
• Note:
• • The WebUSB landing page notification is currently disabled in Chrome

I don't have a log

What happened ?

When I was using an older version of the ESP32 Core (pre 3.x) and using version 3.3.4 of the TinyUSB library, the RGB example worked perfect. Color changed on connect and I could change it further after that. The serial example also worked just fine.

Once I updated to a newer ESP32 Core (3.0.7) and version 3.4.1 of the TinyUSB library, now things are even wonkier. The RGB example only sort of works. The color doesn't change properly upon connecting the browser, but it will change if I manually pick new colors. It's like that line state callback isn't working. Additionally, now, I can't seem to send data from the device to the browser at all. There's no errors, but nothing ever comes through.

How to reproduce ?

On a similar board to mine, use ESP32 Core 3.0.7 and Library version 3.4.1 and try to run the RGB and serial examples
