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

Test HCD interrupt pipe URBs
|
|
Purpose:
|
|
- Test that an interrupt pipe can be created
|
|
- URBs can be created and enqueued to the interrupt pipe
|
|
- Interrupt pipe returns HCD_PIPE_EVENT_URB_DONE
|
|
- Test that URBs can be aborted when enqueued
|
|
|
|
Procedure:
|
|
- Setup HCD and wait for connection
|
|
- Allocate default pipe and enumerate the device
|
|
- Setup interrupt pipe and allocate URBs
|
|
- Enqueue URBs, expect HCD_PIPE_EVENT_URB_DONE, and requeue
|
|
- Stop after fixed number of iterations
|
|
- Deallocate URBs
|
|
- Teardown
|
|
|
|
Note: Some mice will NAK until it is moved, so try moving the mouse around if this test case gets stuck.
