Re: Re: Re: 3.0 device attached to USB 3.0 hub port doesn't respond address device command after resume

[VIKAS SAJJAN C <vikas.sajjan@xxxxxxxxxxx>]

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.

Thanks and Regards
Vikas Sajjan

Hi ,

if i disconnect the hub, after the timeout error , i get these errors...

[  295.496749] hub 4-1:1.0: cannot reset port 3 (err = -71)

After this 3.0 port becomes DEAD, it does not detect any attach /detach.  

even i tired with another hub, same is the issue...

all the cases of suspend / resume works except this case, by that i mean

1. USB 3.0 Device on 3.0 port - Works fine. 
2. USB 3.0 Device on 2.0 port - Works fine.
3. USB 2.0 Device on 3.0 port - Works fine.
4. USB 2.0 Device on 2.0 port - Works fine.
5. USB 2.0 Device on SS hub on 3.0 port - Works fine.
6. USB 2.0 Device on 2.0 hub on 3.0 port - Works fine. 
7. USB 3.0 Device on 2.0 hub on 3.0 port - Works fine.
8. USB 3.0 Device on SS hub on 2.0 port - Works fine.
9. USB 3.0 Device on SS hub on 3.0 port - FAILS.
