Hi,

I have two question about the interrupt-IN transfer with high speed host.

1) How should the toggle bit of data be for an interrupt-IN transfer whose interval is several ms,
i.e., much longer than a microframe?

2) What will cause the host stop to issue the interrupt-IN request, after the host has got one data
packet through the interrupt-IN transfer?

Thanks,

Zhu Xiaolin

The same as full speed, it doesn't change with the interval, it changes with
the transfer.



You must have a read IRP in the queue.
