Are there any issue using both controllers in host mode? USBH_StatusTypeDef USBH_LL_Init(USBH_HandleTypeDef *phost) { /* Init USB_IP */ if (phost->id == HOST_FS) { /* Link the driver to the stack. */ hhcd_USB_OTG_FS.pData = phost; phost...

The Escape key was mapped to 0x00 in the USB HID code, I added it and it works fine but I'm curious to know why it was absent? Bug/oversight, another method used for Escape key detection? #ifdef QWERTY_KEYBOARD static const uint8_t HID_KEYBRD_Ke...

I'd like to use both of the Synopsis USB controllers on the STM32H743VIT6, one as device, one as host, but to do that I understand that the other USB controller is accessed through the USB HS device, which is disabled because of the use of LTDC.Curre...

Can you see the glaring bug, or is it? I left a clue *** some fail returns do not unlock HAL HAL_StatusTypeDef HAL_I2C_Mem_Write(I2C_HandleTypeDef *hi2c, uint16_t DevAddress, uint16_t MemAddress, uint16_t MemAddS...

I added a Linked Resource and tested it on an include line, although the path is the same, it fails.I have zero idea why, does it need another syntax?Path variable:-> REPOSITORY_LOC set as C:\Users\Dev\STM32Cube\RepositoryWith GCC Copiler Include Pat...

So to verify, STM's latest H7xx LL-libraries don't support the use of the USB HS controller for FS operation?

Okay thanks, but I already have host and device working well for CDC and HID, I wonder how much code I'm going to have to rewrite to get this working using the latest HAL, I guess it doesn't allow switching on the fly between CDC and HID?

Reply edited to align with community guidelines. You are ignoring the fact the the GNU compiler is report a warning that the function is void yet returns a value.

I agree, ST managers are hopeless, over a decade now of poor USB support, and they wonder why they're losing market share.

That allows recovery, but standard practice is to leave interface in the same state as when entered, and not depend on external routines to recover the status.You've also overlooked the failing in the HAL_Lock code as #defined, where the return type ...
