I guess I just need to suck it up and setup a Linux guest to see what (if any) parameters work and to rule out driver issues on the guest…
Windows 7 guest drivers from here: http://www.driverscape.com/manufacturers/renesas/usb (NEC 3.0 Controller)
Using Ubuntu 14.04 with a custom complied qemu 2.1 with all the defaults (except PREFIX=/opt/qemu)
With this (uncommented part),
I get:
qemu-system-x86_64: hw/usb/hcd-xhci.c:896: xhci_events_update: Assertion `intr->er_full’ failed.
Aborted (core dumped)
also from dmesg:
[16948.896976] usb 4-4: reset SuperSpeed USB device number 10 using xhci_hcd

Tail end of qemu invocation shell script (showing previous ideas).

Next steps, maybe I should try this with a Linux guest to test the parameters and rule out driver issues?
