Hi All, I was using the SS hub by VIA Labs,inc. what I found is that, there is a firmware update available for this SS HUB. When i went through the Release Notes, they say USB 3.0: Resolved issue with Intel USB 3.0 Host where devices were occasionally not properly re-enumerated after resuming from S3/S4, warm-boot, or cold boot http://www.via-labs.com/en/downloads/documents/VL810-Firmware-V9.5-Release-Note.pdf I upgraded the firmware with their tool (http://www.via-labs.com/en/support/downloads.jsp), with that , this case "USB 3.0 Device on SS hub on 3.0 port" gets resolved.
