Hub Driver is refactored as follows:
This commit update and refactors the Hub Driver as follows:
- Refactored enumeration state machine and stage functions
- Enumeration stage is now incremented
- Combined transfer stages of enumeration into common functions
- Comments updated
- Fixed usbh_hal_disable_debounce_lock() that would cause root_port_handle_events()
to fail the HCD_PORT_CMD_RESET call because the previous port connection interrupt
was not cleared.
The following features were added to the Hub Driver
- Enumeration config descriptor is now fetched in two separate stages
- Header is fetched first to determine the wTotalLength of the descriptor
- Fetching the full descriptor will request exactly wTotalLength bytes
- This works around some non-compliant devices that will babble/return zero
when requesting a length > wTotalLength
- Closes https://github.com/espressif/esp-idf/issues/7799
- Enumeration now stores string descriptors
- The Manufacturer, Product, and Serial Number string descriptors are
now read and stored during enumeration
- String descriptors are now part of usb_device_info_t
- Added unit test to test enumeration
