That this patch: > https://svnweb.freebsd.org/base?view=3Drevision&revision=3D281499 Fixes the problem for me. I'm manually applying it after every kernel update since about a year. I stumbled upon that patch here: > https://lists.freebsd.org/pipermail/freebsd-virtualization/2015-April/003= 499.html It seems other people are affected by this problem as well, though the workaround presented here: > https://github.com/pr1ntf/iohyve/wiki/USB-3.0-PCI-Controller-Pass-through seems worse to me, because it completely disables the xhci driver. Basically I'd like to see the patch land in a released version at some poin= t. Because I lack any knowledge about the FreeBSD development model I'm unable= to determine that state of that patch -- maybe it's on the list already? After one year I just thought maybe it's time to ask. :-) Thanks, -Matthias --=20 You are receiving this mail because: You are the assignee for the bug.=
