I never made any kernel changes related to USB in my github trees, as 
far as I know, so shouldn't be any difference. That original gerrit 
commit was purely for our testing purposes for our system... not really 
something I can support actively.

I have a number of commits pending review that you could try and pull in 
if you really need this now:
https://gerrit.openbmc-project.xyz/#/c/openbmc/meta-phosphor/+/13536/
https://gerrit.openbmc-project.xyz/#/c/openbmc/meta-aspeed/+/13541/
https://gerrit.openbmc-project.xyz/#/c/openbmc/obmc-ikvm/+/12126/
https://gerrit.openbmc-project.xyz/#/c/openbmc/obmc-ikvm/+/13888/

Use these in combination with the two commits at the top of my video-dev 
linux tree for your kernel.

Thanks,
Eddie
