STM32 Virtual COM Port USB-OTG driver

Postby Bumanuu » Tue Sep 05, 2023 8:56 am

Hello, all!
Any help to implement USB host driver for ESP32-S3 of that device:

Linux detects it as
Code: [Select all] [Expand/Collapse]

I have tried to connect to it with modified
esp-idf/examples/peripherals/usb/host/cdc/cdc_acm_host/main/usb_cdc_example_main.c
code, but with no luck:
Code: [Select all] [Expand/Collapse]

  2. E (2369) cdc_acm: cdc_acm_host_open(757): USB device with VID: 0x0483, PID: 0x5740 not found
  3. I (2369) USB-CDC: Failed to open device

Actually, I need VCP driver for STM32 Virtual COM Port, like those:
esp-idf/examples/peripherals/usb/host/cdc/cdc_acm_vcp/managed_components/espressif__usb_host_ftdi_vcp
esp-idf/examples/peripherals/usb/host/cdc/cdc_acm_vcp/managed_components/espressif__usb_host_cp210x_vcp
esp-idf/examples/peripherals/usb/host/cdc/cdc_acm_vcp/managed_components/espressif__usb_host_ch34x_vcp

In attachment is capture of PC <-> STM32 VCP exchange (plug, open serial port, some data exchange, close, unplug).
