A host balances the bus access requirements of all control pipes and pending transactions on those pipes to provide a “best effort” delivery between client software and functions on the device. This policy is the same as the USB 2.0 policy. Are you sending isochronous or bulk transcation? With isochronous transcation, you will have guaranteed bandwidth. For bulk, it will be based on best effort.
Thanks

David-san,
Thank you for prompt reply.
Sorry for my wrong explanation.
Please let me ask you just simple question.
Is there configuration register regarding USB transaction priority level in 66AK2H12?

For USB transcation,what type of transcation, bulk, interrupt, control, or isochronous transcation?
Thanks

This is tied internally, so it is not configurable.
For the next revision of device, we do not plan to drive priority for write or read operation.
Thanks
