Note: The Auto RxDetect mode has been designed to recognize 3.0 hosts and
devices and present 3.0 terminations to them when they are plugged in.
However, some cases have timing that can cause the Host and Device not
to connect or to go into USB 2.0 mode. If either of these timing cases occurs,
click the Momentary Disconnect button on the toolbar to cause a
Disconnect/Reconnect cycle of the VBus. If cycling does not work, disable
and then re-enable the xHCI Host controller driver in the Windows 7
Device Manager of your PDK.
For Polarity Inversion, Downstream and/or Upstream, select On, Off, or Auto.
For Simple Filters, you can Filter Out Logical Idles and SKPs, Filter Out LUP/LDN, or
Filter Out ITP.
Truncate Data Fields
Truncate the data fields in a Data payload Packet to the length specified in the pull-down
selection.
Note: Truncating the payload will allow for more packets to fit in a trace, but it has
the potential to prevent accurate decoding to higher layers (transfers, SCSI,
etc).
