I want to pass HD Webcam USB device to the FreeBSD running in qemu.
I use following command to start the emulated system:
During the startup I get following warning (it is actually displayed 3 times):
qemu-system-x86_64: Warning: speed mismatch trying to attach usb device "HD Webcam" (high speed) to bus "usb-bus.2", port "2" (full speed)
When I
Device 2.0, Port 2, Speed 480 Mb/s, Product HD Webcam
I am wondering what is wrong.
FreeBSD supports high speed mode USB.
I have 3 suspicions.
1. FreeBSD image for qemu is missing some USB drivers.
2. I need to pass more/different arguments to qemu on start.
3. My USB device is available inside FreeBSD, but it is not listed by
Does anyone know what is going on?
EDIT
