Darian Leung	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.	2023-11-24 20:57:03 +08:00

Darian Leung	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	2021-08-24 23:28:00 +08:00
