Implementation of USB Host VCP (CDC) on STM32F105 to Communicate and Charge an Android Tablet

[Ereaey]

Hello Zephyr Team,

I hope this message finds you well. I am currently working on a project that requires communication with, and charging of, an Android tablet utilizing USB Host VCP (CDC) through an STM32F105.

The primary objective of this project is to establish a reliable communication link between our embedded system (using the STM32F105) and an Android tablet, while also being able to charge the tablet through the same connection. While exploring the functionalities provided by the Zephyr RTOS, it seems like the specific support for USB Host VCP (CDC) on the STM32F105 is not available or straightforward.

Given the scenario, I’m exploring the possibility of using the STM32 HAL to achieve the required functionality. I'm reaching out to inquire if anyone in the community has engaged in a similar endeavor or has experience interfacing USB CDC with the HAL while running Zephyr.

Any insights, examples, or guidance will be immensely valuable to navigate through this implementation. If there are alternative approaches or considerations that might be worthwhile to explore within Zephyr for this use case, I'm all ears.

Thank you so much for considering my query. Looking forward to any pointers or discussions that can assist in resolving this
