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 |
