Win7 Pro (64) guest still fails to shutdown since 7.0.16

It's still toast. Though it shuts down clean with USB 2.0 enabled, and the TI calculator filter enabled, Win7 fails to actually find the calculator rendering the TI software useless. Checking the "Any USB" box in the guest cfg USB filter section reverts to shutdown halt on black screen and the process has to be forced closed, usually via a different TTY because the host DE semi-hangs. Also haven't found the 7.0.14 code to test patching 7.1.X with the USB regression.

EDIT1: other unrelated problem prevalent at moment (re: segfault core dump in the log) with VirtualBox overall
EDIT2: dumb mistake, booted wrong kernel regarding EDIT1, the USB problem remains.

I have been following the same path as @wfv but have slightly different experiences.
Firstly, disabling USB support seems to enable a clean start and shutdown. However, re-enabling USB2 results in Win7 hanging (and my touchpad actions in UBuntu being largely ineffective!) but right clicking on the VMbox icon prompts me to be able to 'stop the virtual machine'. Normal Ubuntu service then resumes.

As an aside, as a matter of course, I always have to mess about with the bridge adaptor in the network settings -swapping between the two available names and back again to gain internet access. I have got used to this other irritation but what was interesting is that with USB disabled, I did not have to do this at any time during my trials.

Do these two factors suggest there is something badly wrong with the USB support?

For further info, in addition to the latest VMbox, I am using both the latest guest additions and extension packs.
Also I am using a Dell laptop and built in touchpad and no external mouse.

@ chrisd -

Network connection could be a different issue however, that you experience non-issue with network when USB2 is disabled is beyond my skill level (and i use that term exceedingly loosely for lack of better term ) - otherwise in reply to your question, yes something badly wrong with USB support for Win7 - don't know where Oracle has the code and commits since website changed recently to delve into deeper - bisect 7.0.14 vs 7.0.16 USB fixes.

@wfv
For info, I access the internet via Wifi connected dongle - so its not even USB!
However, I'll leave this issue as we're drifting off topic.
