Cannot install USB host driver after installing i2c Driver in ESP32-S3

[DxPian]

Code: [Select all] [Expand/Collapse]

1.  
2. In ESP32-S3, Installing USB host driver fails once I2C driver was installed already.
3. If I uninstall I2C driver, USB host driver successfully installed.
4. Bellow is a brief sample code to reproduce the issue.
5. Error code = 261(ESP_ERR_NOT_FOUND)

Hello,
i had the same problem and i resolved it using ESP_INTER_FLAG_LEVEL2 as shown below:
const usb_host_config_t host_config = {
.intr_flags = ESP_INTR_FLAG_LEVEL2,
};
