+UHCI Host Controller no longer present with -usb
+
+If on an up to date 12.04 install and I start a VM with:
+$ qemu -m 192 -serial none -chardev null,id=chardevmon -pidfile /tmp/pid -daemonize -nographic -monitor tcp:127.0.0.1:4444,server,nowait -net user,hostfwd=tcp:127.0.0.1:4422-:22 -usb -rtc base=utc -name qatest-vm -uuid ded3a46b-bb60-43f4-8113-d041aeb93cdf -hda libvirt/qatest/qatest.qcow2
+
+Then use the 'info usbhost' in the monitor, I get:
+$ echo 'info usbhost' | nc -q 1 127.0.0.1 4444
+(qemu) info usbhost
+husb: using sys file-system with /dev/bus/usb
+$
+
+In Oneiric and eariler, 'info usbhost' would should a UHCI Host Controller. Eg:
+$ qemu -m 192 -serial none -chardev null,id=chardevmon -pidfile /tmp/pid -daemonize -nographic -monitor tcp:127.0.0.1:4444,server,nowait -net user,hostfwd=tcp:127.0.0.1:4422-:22 -usb -rtc base=utc -name qatest-vm -uuid ded3a46b-bb60-43f4-8113-d041aeb93cdf -hda libvirt/qatest/qatest.qcow2
+echo 'info usbhost' | nc -q 1 127.0.0.1 4444
+QEMU 0.14.1 monitor - type 'help' for more information
+(qemu) info usbhost
+husb: using sys file-system with /dev/bus/usb
+  Device 1.1, speed 12 Mb/s
+    Hub: USB device 1d6b:0001, UHCI Host Controller
+
+This breaks QRT/scripts/test-qemu.py and appears to be a regression, but I am not sure if it is a 3.2 kernel issue or a 0.14.1 vs 0.15 issue.
+
+hm, i couldn't reproduce this with 0.15.0+noroms-0ubuntu2 on top of 3.2.0-1-generic
+
+also couldn't reproduce it after an upgrade just now.
+
+I did a dist-upgrade and this is still reproducible:
+$ uname -a
+Linux sec-precise-i386 3.2.0-2-generic #5-Ubuntu SMP Mon Nov 28 18:09:32 UTC 2011 i686 i686 i386 GNU/Linux
+$ dpkg -l | grep qemu
+ii  qemu-common                     0.15.0+noroms-0ubuntu6                  qemu common functionality (bios, documentation, etc)
+ii  qemu-kvm                             0.15.0+noroms-0ubuntu6                  Full virtualization on i386 and amd64 hardware
+ii  qemu-utils                             0.15.0+noroms-0ubuntu6                  qemu utilities
+
+My testing is: my amd64 Oneiric kvm laptop boots an i386 12.04 non-kvm guest which boots a minimal install i386 6.06 image. All of this is verified to work when booting an i386 11.10 non-kvm guest (which boots the same 6.06 image).
+
+oh, sorry, i'll try without kvm.
+
+Ok, I see now - other usb devices are there, but not the EHCI or UHCI controller.
+
+there have been quite a few changes upstream to the usb code.  I'm building latest qemu-kvm to test with.
+
+Latest qemu-kvm from upstream has the same problem.
+
+Reproduced with today's qemu git head as well.
+
+Looking through old bug tickets... is this still an issue with the latest version of QEMU, or could we close this ticket nowadays?
