I've few questions about QEMU:
=3B
1) I read in QEMU's official documentation that in case of using host syste= m devices "USB devices requiring real time streaming (i.e. USB Video Camera= s) are not supported yet". Also there is no isochronous transfer based virt= ual USB device in QEMU. I want to know what is current status of Iso. suppo= rt in QEMU? Can I test my Linux based USB host application for ARM =3Bw= ith physical iso devices in host USB port?
=3B
2) I found a function "ohci_service_iso_td" in usb-ohci.c file in QEMU sour= ce code.
=3B
3) I am developing a Linux based USB device using Gadget API. Does QEMU pro= vide USB function controller emulation in such a way that I can run plug th= is USB device at run time with host machine and can test it?

Can I test my Linux based USB As of commit 8e65b7c04965c8355e4ce43211582b6b83054e3d I have been able to pass audio devices to a VM with good success (though I use qemu-kvm, not just qemu). I just started looking at web cameras and not having much luck yet.
