Alternatively, a host controller implementation is allowed to traverse the entire asynchronous schedule list
(for example, observed the head of the queue (twice)) before setting the Advance on Async status bit.
The software may re-use the memory associated with the removed queue heads after it observes the
Interrupt on Async Advance status bit is set, following assertion of the doorbell. The software should
acknowledge the Interrupt on Async Advance status as indicated in the USBSTS register, before using the
doorbell handshake again

EHCI uses two bits to detect when the asynchronous schedule is empty. The queue head data structure (see

the head of the reclaim list. host controller also keeps a 1-bit flag in the USBSTS register (Reclamation)
that is cleared when the host controller observes a queue head with the H-bit set. The reclamation flag in
the status register is set when any USB transaction from the asynchronous schedule is executed (or
whenever the asynchronous schedule starts, see
Start Event.”
If the controller ever encounters an H-bit of one and a Reclamation bit of zero, the controller simply stops
traversal of the asynchronous schedule.
An example illustrating the H-bit in a schedule is shown in
