PCM2900C: USB 2.0 compliance testing - HS US Signal Quality

Part Number: PCM2900C

USB 2.0 compliance testing using PCM2900C. 

The USB-IF test tool (XHCI HSETT) recognizes the device, but the TEST_PACKET command is not successful. 

I heard that there may be no TEST_PACKET processing program. 

Could you please let me know if there is a cause or a solution to this problem?
