9.2i EDK- opb_usb2_device_v1_00_a, IP core does not support Data PID sequencing for isochronous data transfers in high-speed mode

Description

The Xilinx USB IP core does not support Data PID sequencing for isochronous data transfers in high-speed mode. In high-speed mode, Data PID sequencing (DATA0, DATA1 and DATA2) can be used for isochronous data transfers when the host sends more than one transaction per micro frame.

Solution

The core is tested with a host running Windows XP SP2 OS that sends only one transaction per micro frame. The test uses only DATA0.
