BSOD win7 x64 everytime

[oxoocoffee]

This might be related to bug #6922 that I reported.

As reported in bug 6922 vbox fails to start when Clear 4G USB connected but virtualbox.exe is running in Task Manager. Now if I pull out the Clear 4G USB card from laptop while virtualbox.exe process is running (no ui visible) windows crashes to BSOD every time. If I first kill virtualbox.exe process first than pulling out USB is not a problem. It took me some time to notice this since my first impressions were that this was purely random and it was problem with Clear. Also there seems to be a problem with this version with USB external floppy (also reported by me) failing to mount floppy in guest (windows XP x32). Below is log of a crash from my host (Win7 x64)
