Hi.

 

We have several HP Z440 machines that me and my colleagues use with high speed cameras from Point Grey (Grasshopper3).  We had problems with 2 different BIOS versions where the USB system would stop working or provide corrupted data.  We found a version that does work, but we still have problems with corruption.  Point Grey has been unable to reproduce the problems and I believe that it may be due to the BIOS given we already there were some issues. The 3 versions we've used are:

 

* Version: M60 v02.14 Release Date: 02/18/2016 : **works**
* Version: M60 v02.26 Release Date: 09/06/2016 : **doesn't work**
* Version: M60 v02.31 Release Date: 12/14/2016 : **doesn't work**

2.31 is the most recent version available AFAICT.  I can't find any mention of USB3 in the revision history, so I don't know if this issue is known.  We used a 3x kernel a while ago as well as 4.4.0-36-generic and now we are using:

 

4.4.0-66-generic #87~14.04.1-Ubuntu SMP Fri Mar 3 17:32:36 UTC 2017 x86_64

All have exhibited the same behavior.  I haven't been able to find any information in a bunch of searches.  I can't think of anything else to do, but beg for help from this forum.

 

Any suggestions for how we can verify the BIOS is/isn't the cause?  If it is the cause, how can we get it fixed?

 

Thanks,

n
