When catching USB packets from the XHC20 interface they are always displayed in
the Packet List Pane as having the Destination Host. Although I am pretty new
to USB protocols I am of the opinion some of the packets should have host
listed as the source and not the destination. As there are no packets listed
what-so-ever as having the host listed as source I am certain there is a
problem here. If I try plugging in my keyboard while capturing the enumeration
sequence this should involve packets initiated from both the host and the
device (keyboard) but they are all listed as originating from the device.
