STM32G0B1 USB HID Host

[AWack]

Hi,

I´m trying to get a USB HID Host running on a STM32G0 with STM32CubeMX and STM32CubeIDE.

Unfortunately all examples or topics in ST communities don´t really work. Also the USB wiki doesn´t provide a clear explanation of all commands available in the libraries. Maybe it´s also a problem, that the examples for the G0 don´t use FreeRTOS...

Can anyone help which commands (in which order) I´ve to use to read data (in my case from a CP2110 USB to UART bridge)? 

My current code:

usbState = USBH_InterruptReceiveData (&hUsbHostFS, buf, 5, 0);

usbState = USBH_Get_DevDesc (&hUsbHostFS, 10);

USBH_SetAddress (&hUsbHostFS, 0x28);

usbState = USBH_OpenPipe (&hUsbHostFS, 0, 0x28, 1, 0, 0, 8);

USBH_HID_SetReport(&hUsbHostFS, USB_H2D, 0x50, &buf, 10); // Used to configure the CP2110

USBH_HID_GetReport(&hUsbHostFS, USB_H2D, 0x01, &buf, 3); // Attempt to read data

Best regards,

Achim

Hello,

As far as I know the CP2110 does not support native CDC ACM virtual port com, which requires specific driver from host side. Otherwise you could get some host examples supporting FreeRTOS from other STM32 packages STM32F7, STM32H7 ... which can be easily ported to STM32G0 platform

Hi,

as far as I know, in Windows no special driver is needed to see the CP2110 as a HID device.

The initialization fails at USBH_FindInterface(...);

Here is the log:
