Bug ID: 225794
           Summary: VM images for 12.0-CURRENT have problem with USB 3.0
           Product: Base System
           Version: CURRENT
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern

Created attachment 190466
output of camcontrol devlist before USB drive is inserted

Beginning with 12.0-CURRENT VM image:


and continuing with 12.0-CURRENT VM images:


when a USB flash drive inserted into a USB 3.0 port is accessed (in this case
via gpart show), the console hangs for 10-12 minutes then emits the
error messages seen in the attachment.

The UFS filesystem on the USB flash drive cannot be mounted.

If the USB flash drive is connected via the attached USB 2.0
controller, everything is good.

This problem is not manifested in any 10.4-STABLE or 11.1-STABLE VM

The host system is CentOS EL7 7.1708.

VirtualBox version is 5.2.6.

The USB 3.0 controller uses a VIA chipset.

System is for test purposes only, so it is easy to try anything that
might help resolve this problem.
