095b541125 change(usb/host): Remove some handler function event flags
This commit removes internal event flags in the USB Host Library event handling
functions (i.e., usb_host_lib_handle_events() and usb_host_client_handle_events()).

Previously, these flags were added to reduce the number of times semaphores
were given. However, these flags were removed as the performance gain is
negligible and made the logic more complicated.

For usb_host_client_handle_events(), the following flags were removed:

- Remove 'events_pending' flag. The semaphore is now always given
- Remove 'blocked' flag. The 'handling_events' flag is already sufficient
- Critical sections are now shortened due to simplication of semaphore usage.

For usb_host_lib_handle_events(), the following flags were removed:

- Remove 'process_pending' flag. The semaphore is now always given
- Renamed 'blocked' flag to 'handling_events'

16c37f9db1 change(usb/host): Remove data buffer headers from URBs
This commit removes the ability to reserve a header in the data buffer of an
allocated URB. The header was required for a now defunct implementation of a
synchronous USB Host library API. Thus, headers are no longer required in
URB data buffers.

f48f433d5b fix(usb/host): Do not abort on string descriptor overflow
Some devices return full LANGID table, even if short LANGID table was requested.
No memory overflow occurs, because we have allocated enough memory for transfers to the
default pipe. So we can ignore the error and continue with string desc fetching.

Some component test apps do not use the "set(COMPONENTS main)" command in their

This commit trims the build of multiple component test apps:

bab1c61a4c usb_host: Refactor USBH and USB Host Library calls to HCD
This commit refactors the USBH and the USB Host Library in the following ways:

- USBH now presents an abstraction of an endpoint (via usbh_ep_handle_t)
    - Added separate functions to enqueue/dequeue URBs to a particular endpoint
    - USB Host Library no longer calls HCD API directly. Calls USBH endpoint API
      instead.
- Renamed "notif_cb" to "proc_req_cb" (Processing Request Callback)
    - This is to avoid confusion with FreerTOS task notifications and Host
      Library client event notifications.
    - The processing functions of each layer (i.e., "xxx_process()") request
      calls via the "proc_req_cb"
    - The main handling function (i.e., usb_host_lib_handle_events()) is
      responsible for calling the required "xxx_process()" of each layer

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.

e17e066828 usb_host: Add check to prevent submitting already inflight transfers
This commit adds a simple flag/check in the USB Host Library that prevents
users from submitting a transfer that is already inflight.

- A transfer is considered inflight as soon as it is submitted by calling
usb_host_transfer_submit() or usb_host_transfer_submit_control()
- An inflight transfer remains inflight up until right before its callback
is called by one of the USB Host Library handler functions.

This commit fixes incorrect usage of memset() in the HCD's various

were simply setting the first qtd to a non zero value (i.e., the length of

However, no bug occurred as the subsequent _buffer_fill_...() functions would
overwrite the QTD list anyways.

global: add dependency on esp_timer component and include esp_timer.h
Some components were including esp_timer.h without declaring a
dependency on esp_timer component. This used to work due to a
transitive public dependency on esp_timer from freertos component.
Add explicit dependencies where needed.
Also some source files were using esp_timer functions without
including the header file. This used to work because esp_timer.h was
included from freertos port header file. This commit adds esp_timer.h
includes where needed.

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

854127a57c usb: USB Host stack uses USB PHY driver
This commit updates the USB Host stack to use the USB PHY driver. The
USB PHY and the OTG Controller should now both be setup/deleted using
usb_new_phy() and usb_del_phy() respectively.

- The hcd_install() now expects the USB PHY and OTG Contorller to be
    already setup before it is called
- usb_host_install() now has an option to skip calling usb_del_phy() if
    the user wants to setup their own USB PHY (e.g., in the case of using
    and external PHY).
- CDC-ACM and MSC examples/test updated to use internal PHY

5a2ef15565 usb: HCD multiple fixes
This commit fixes the following bugs in the HCD

- HCD control pipes fill incorrect transfer size

_buffer_fill_ctrl() would fill the transfer descriptors length with
wLength instead of transfer->num_bytes. Therefore, the remaining length
would be incorrect when a control transfer requests more bytes than are
available.

- Fix USB_TRANSFER_FLAG_ZERO_PACK behavior

The previous behavior of USB_TRANSFER_FLAG_ZERO_PACK was incorrect, and did not
support interrupt pipes. A zero length packet can now be added to Bulk/Interrupt
OUT transfers where the length is a multiple of the endpoint's MPS.

- Fixed HCD port suspend and resume test case

Halting a control pipe mid control transfer can lead some test devices to get stuck

6a12e28333 usb: Fix USBH handling of disconnections
This commit fixes how the USBH handling of a sudden device disconnection,
more specifically handling of device gone.
- Previously the USBH would only halt, flush, and dequeue the device's
default EP, then send a device gone event to the Host Library layer.
- Now the USBH will also halt and flush all non-default EPs, allowing
all of the URBs to be dequeud.
- Some internal object members are now protected by a mutex instead of
a spinlock.

0c758c8557 usb: Fix how the HCD handles sudden disconnection
This commit fixes how the USB Host HCD handles sudden disconnections.

Bugs:
- HW channels remain active when the port suddenly disconnects, and
previously the channel would be disabled by setting the disabled bit,
then waiting for a disabled interrupt. However, ISOC channels do not
generate the disabled interrupt when the port is invalid, thus leading
to tasks getting indefinitely blocked in hcd_pipe_command().

Fix:
On a sudden disconnection, forcibly treat all channels as halted even
if their HCCHAR.ChEna bit is still set. We do a soft reset after a port
error anyways, so the channels will eventually be reset.

18f9dabce1 USB: Change IRP to URBs
This commit changes the IRP (I/O Request Packet) structure to
the URB (USB Request Block) in order to represent USB transfers
in the host stack. The new URB strcuture:
