• BINTERVAL: bInterval parameter
This field corresponds to the bus access period of the pipe.
For Interrupt pipe, this field corresponds to the desired period from 1 ms to 255 ms.
For isochronous pipe, this field corresponds to the desired period calculated as this: 2^(BInterval) * 1 ms.
For bulk or control pipe, this field corresponds to the desired period from 1 ms to 255 ms.
This field is cleared upon sending a USB reset.
• PTYPE: Pipe Type
This field contains the pipe type.
