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.
Closes https://github.com/espressif/esp-idf/issues/8748
This commit updates the USB Host Library as follows:
- usb_helpers.h
- Removed dependency on USB Host Library API
- Added function to print string descriptors
- usbh
- Fixed bug where an interface/endpoint could be claimed/allocated multiple times
- Removed redundant device ref_count change
- Added unit test for USB Host Library API usage
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
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
Closes https://github.com/espressif/esp-idf/issues/8061
This commit updates the USB Host Library API in the following wasy:
- usb_host_client_handle_t and usb_device_handle_t made into struct pointers
to generate compiler warnings about conflicting handle types
- usb_host_client_config_t changed to future proof API for Synchronous Clients
- Added usb_host_lib_unblock()
- Added usb_host_device_addr_list_fill()
- Return of usb_host_device_free_all() updated to indicate whether there
are still devices yet to be freed.
- Blockg APIs are now marked explicitly
- Fixed a bug in usb_host_transfer_submit_control() when checking the bEndpointAddress
of a control transfer.
Tests are also refactored to move some common macros into shared headers
Closes https://github.com/espressif/esp-idf/issues/7786
- This commit adds the API documentation for the USB Host Library.
- Warnings about the beta API are also added.
- usb_host_misc.h renamed to usb_helpers.h
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
