USB host issue in CDC mode

[iSaeed62]

Hello everyone,
I am developing firmware for the STM32F7508-DK discovery board, and I'm utilizing TouchGFX for the GUI aspect of the project. However, I am encountering a problem when enabling USB-FS HOST functionality. The GUI and other peripherals such as UART and I2C are functioning correctly. However, as soon as I connect a device to the USB port on the discovery board, the device is detected, but subsequently, the entire board freezes. Specifically, the USBH_UserProcess callback is invoked, and the HOST_USER_CONNECTION line is executed, but afterwards, the system becomes unresponsive. I would greatly appreciate any insights or potential solutions to address this deadlock issue.

Thank you
