THIS IS URGENT.I have had Ux_Device_CDC_ACM (and an enhanced version of it) working for months, and it has since BROKEN. I use the NUCLEO-U5A5ZJ-Q to baseline.Here is what I did:1) Created a new Ux_Device_CDC_ACM project.2) Used STM32CubeIDE Version...

I have been struggling trying to implement two CDC-ACMs on a NUCLEO-U5A5ZJ board on the USB_OTG_HS bus and am having great difficulty. I have been successful getting them to appear on Device Manager, but I have been unsuccessful getting them to tran...

I have implemented a dual CDC-ACM USBX device, and would like to incorporate a mechanism to programmatically differentiate the two ACM's at the Host. One mechanism would be to have each ACM carry with it it's own Serial Number, but I am at a loss as...

Never mind. Apparenty the default setting for the project is EWARM not STM32CCubeIDE.

The issue is that the fifos were not appropriately initialized. Since there was a lack of documentation, I extended the initialization at the end to read as follows: VOID USBX_APP_Device_Init(VOID) { /* USER CODE BEGIN USB_Device_Init_PreTreatment...

Is there an example of creating dual ACM's using a high speed USB OTG HAL? I can get the two to appear, and have seen the USBX FS USB instantiation. The biggest difference that I cannot map from the FS example to the HS example is that during initi...

In looking at all the examples I could find for dual ACM implementations, one portion of app_usbx_device.c are several lines that are directed at USB_FS operation: HAL_PCDEx_PMAConfig(&hpcd_USB_FS, 0x00, PCD_SNG_BUF, 0x40);HAL_PCDEx_PMAConfig(&hpcd_U...

I haven't yet gotten 2 ACMs to actually transmit data. Is there a good procedure to follow to implement this on a HS-OTG platform - specifically the STM32U5A5?
