Hi Sarah, I am trying to debug a situation where when booting up my system with 3.0.0-rc7, the xhci_hcd detects my usb3 WD disk and usb3 hub. However it doesn't detect my usb3 Buffalo disk behind my hub. On my Panther point system's root hub port 3 has the WD disk port 4 has the VIA 4-port usb3 hub Using lsusb -t, I expected bit0 to represent the actual connect state of the device under the hub port status. It shows a '0', meaning nothing is connected (for the VIA hub). Hub Port Status: Port 1: 0000.02a0 5Gbps power Rx.Detect Port 2: 0000.02a0 5Gbps power Rx.Detect Port 3: 0000.02a0 5Gbps power Rx.Detect Port 4: 0000.02a0 5Gbps power Rx.Detect Of course, if I unplug the disk and re-connect, it works as expected. I am trying to understand the situation in which the hub would not see a device is connected (even when the power is enabled to the port it seems). I am not sure what logs to attach so I haven't attached any. Any guidance on where to look or what to look for would be appreciated. :-) Thoughts?
