Problems with BIOS

HP Recommended
HP Z440
Linux

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
