I'm tryng to use ES32-S2 as usb host device to read a flash drive, but alway get de error below: 14:45:32.663 -> ESP-ROM:esp32s2-rc4-20191025 14:45:32.663 -> Build:Oct 25 2019 14:45:32.663 -> rst:0x1 (POWERON),boot:0xb (SPI_FAST_FLASH_BOOT) 14:45:32.663 -> SPIWP:0xee 14:45:32.663 -> mode:DIO, clock div:1 14:45:32.663 -> load:0x3ffe6100,len:0x524 14:45:32.663 -> load:0x4004c000,len:0xa50 14:45:32.663 -> load:0x40050000,len:0x28cc 14:45:32.663 -> entry 0x4004c18c 14:45:33.073 -> E (776) HUB: Bad transfer status: CHECK_SHORT_DEV_DESC 14:45:33.073 -> E (776) HUB: Stage failed: CHECK_SHORT_DEV_DESC

I´ve tried with platformIO and Arduino IDE and alway get the same error

[env:esp32-s2-saola-1] platform = https://github.com/platformio/platform-espressif32.git#feature/arduino-upstream platform_packages = framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git#2.0.3 board = esp32-s2-saola-1 framework = arduino

I see this problem with one device. The workaround is to plug in the device then click the ESP32 board reset button.

The device works on Ubuntu so I am pretty sure the problem is with the ESP32 usb host stack.

Hi, thats possible, as the esp-idf host stack is still evolving and i didnt update library for some time.

BTW thanks for PIO setup, it helps me to test with it
