Loading uhci as a module is sufficient to trigger the messages. No device was attached during the output below; in other tests I noticed that uhci appears to not see any device that VMware has attached. This was working just fine with the old stack. The controller appears as: none3@pci0:2:3:0: class=0x0c0320 card=0x077015ad chip=0x077015ad rev=0x00 hdr=0x00 vendor = 'VMware Inc.' class = serial bus subclass = USB Here's some debugging output: Copyright (c) 1992-2009 The FreeBSD Project.
