Implementation of HCD functions for STM32

[ghost]

When trying to embed the library in a third-party project, following the instructions, or to build an example from the library for STM32 in host mode, the same errors of lack of implementation (definition) of some functions related to HCD appear.

Do I understand correctly that the implementation of these platform-dependent functions falls on the shoulders of the developer using the library?

If I'm wrong, please tell me where to find the implementation for STM32F407VG, because definitions for only some devices are available in the source files.

it is not yet implemented. the host stack only support some lpc, imxrt (ehci, ohci) and rp2040

How soon do you plan to add? Are there any relatively accurate predictions?
