Qemu has problems with usb apparently.
While passinthrough this:
On linux the port is constantly reseting itself.
And on m$$ gust driver shows with a yellow bang.
So far I've used qemu with the following usb devices:
The names are shortened in my examlpe but those were picked from qemu -device help
To passthrough usb do I have to use the same chipset as the host?
For instance my host has ohci but I used uhci in qemu.
The reason that I used uhci is because I don't see a standar ohci chipset option in qemu, they all seem platform specific, apple ohci, tegra ohci, etc.
Another test I did was passthgrough a usb 2.0 device via xhci port on linux but it goes out of control.
I wish xhci could handle backwards compatability flawlessly.
I'd appreciate if anyone know how have a painless usb experience with a qemu guest.
