7010349a9a usb_host: Hub driver skips fetching string descriptors if their index is 0
When a USB does not support a particular string dsecriptor (e.g.,
manufacturer, product, and serial number), the string descriptors corresponding
index will be set to 0 in the device descriptor (e.g., iManufacturer, iProduct,
iString).

Previously, the Hub driver would always attempt to fetch the all three string
descriptors, thus leading an error in CHECK_SHORT_SER_STR_DESC if the device
did not support the descriptor.

This commit fixes the Hub drvier by skipping the enumeration stages of a
particular descriptor if its index is 0 (i.e., not supported by the device).

6ae151db8c usb_host: Fix error when fetching LANGID table
USB devices may support string descriptors in multiple languages. The supported
languages are stored in a LANGID table, which itself is a string descriptor at
index 0.

When fetching the LANGID table itself, the USB 2.0 specification does not
specify what LANGID to use, thus the Hub driver would use the default LANGID
"ENUM_LANGID". However, this would cause some devices to stall.

This commit fixes the issue by always requesting the LANGID table itself using
a LANGID of 0.

22c152c388 usb: Hub Driver and USBH recover port automatically after disconnection
This commit updates the Hub Driver and USBH as follows:
- Updated communication mechanism between Hub Driver and USBH
    - USBH notifies the Hub Driver via Hub request callback (usbh_hub_req_cb_t)
    - Hub Driver notifies the USBH via usbh_hub_pass_event()
- Hub Driver now defers all event handling to hub_process.
- Hub Driver and USBH will now automatically recover the port after a disconnected
    device has been closed.
- Fixed incorrect assert in usbh_dev_close()

1aad12468a usb: Hub Driver Update and Refactor
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

accbaee57c Add USB Host Library
This commit adds the preliminary version of the USB Host Library. This commit contains:

- USBH (USB Host Driver)
- Hub Driver that only supports a single device and device enumeration
- USB Host Library (asychronous API)
- Test cases for USB Host Library asychronous API

The following changes were made to the existing HCD:
- Removed HCD_PIPE_STATE_INVALID. Pipes are no longer invalidated
- Changed pipe commands to halt, flush, and clear. Pipes need to be manually
  halted, flush, and cleared.
- Halting and flushing a pipe will execute the pipe callback if it causes a
  HCD_PIPE_EVENT_URB_DONE event
