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 ISOC pipe URBs
|
|
|
|
Purpose:
|
|
- Test that an isochronous pipe can be created
|
|
- URBs can be created and enqueued to the isoc pipe pipe
|
|
- isoc pipe returns HCD_PIPE_EVENT_URB_DONE for completed URBs
|
|
- Test utilizes ISOC OUT transfers and do not require ACKs. So the isoc pipe will target a non existing endpoint
|
|
|
|
Procedure:
|
|
- Setup HCD and wait for connection
|
|
- Allocate default pipe and enumerate the device
|
|
- Allocate an isochronous pipe and multiple URBs. Each URB should contain multiple packets to test HCD's ability to
|
|
schedule an URB across multiple intervals.
|
|
- Enqueue those URBs
|
|
- Expect HCD_PIPE_EVENT_URB_DONE for each URB. Verify that data is correct using logic analyzer
|
|
- Deallocate URBs
|
|
- Teardown
