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

Test a port sudden disconnect with an active ISOC pipe
Purpose: Test that when sudden disconnection happens on an HCD port, the ISOC pipe will
- Remain active after the HCD_PORT_EVENT_SUDDEN_DISCONN port event
- ISOC pipe can be halted
- ISOC pipe can be flushed (and transfers status are updated accordingly)
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
- Trigger a disconnect after a short delay
- Check that HCD_PORT_EVENT_SUDDEN_DISCONN event is generated. Handle that port event.
- Check that both pipes remain in the HCD_PIPE_STATE_ACTIVE after the port error.
- Check that both pipes pipe can be halted.
- Check that the default pipe can be flushed. A HCD_PIPE_EVENT_URB_DONE event should be generated for the ISOC pipe
because it had enqueued URBs.
- Check that all URBs can be dequeued and their status is updated
- Free both pipes
- Teardown
