This commit updates how the USBH handles device creation and enumeration so that upper layers (such as the Hub driver) can use the USBH API for enumeration instead of calling the HCD. USBH Updates: USBH now creates unenumerated devices set to address 0 with no device/config descriptor. A newly created device can be opened and communicated with immediately (using control transfers). This allows the Hub driver to call the USBH instead of the HCD. Summary of USBH changes: - Added new APIs to add/remove a device. Devices are now created as unenumerated and can be immediately opened and communicated with. - Added new APIs to enumerate a device (see 'usbh_dev_set_...()' functions). Device must be locked (see 'usbh_dev_enum_lock()') before enumeration functions can be called. - Added UID for each device. This allows the particular USBH without needing to use the device's handle (which implies opening the device). Hub Driver Updates: Hub driver now calls the USBH for enumeration. Summary of USBH changes: - Replace all 'hcd_pipe_...()' calls with 'usbh_dev_...()' calls - Refactored port event handling to fit with new USBH API - Updated to use UID to uniquely identify devices without opening them USB Host Updates: - Reroute USBH control transfers to clients and hub driver |
