[Qemu-devel] [Bug 1056668] Re: qemu-system-arm crash at startup with -usbdevice

[Peter Maydell]

Well, it's certainly a bug that we crash (and I'll look into that).
However, the vexpress-a9 model does not have any USB controller, so a
fix for this bug would just make us print a nicer error message instead
of crashing...
