STM32WBA65RI USB Host mode not working

[noela]

I've been able to get USB Host working on Nucleo F767I board, but I can seem to get it working on STM32WBA65RI part.   I've tried the following two boards combinations:

1. MB2130A on MB1801D (STM32WBA65I-DK1)
2. MB21230A on MB2143A   (Nucleo-WBA65RI) 

I've tried the following projects:

1. STM32CubeWBA/Projects/NUCLEO-WBA65RI/Applications/USBX/Ux_Host_HID
2. STM32CubeWBA/Projects/NUCLEO-WBA65RI/Applications/USBX/Ux_Host_HID_Standalone
3. My own STM32CubeMX based project.

I've done all my builds (both the working F767 and failing STM32WBA) using STM32CubeIDE.   I've been able to build, flash, and debug into the executable in all cases.   

A fresh clone of STM32CubeWBA from github, I see the expected printed out:

USB Host library started.

Starting HID Application
Connect your HID Device
**** USB OTG HS in HID Host ****

However, plugging devices in CN9, does not result in them getting detected.   Placing a breakpoint on _ux_hcd_stm32_interrupt_handler does not appear that it ever gets called.
