Hi,

It is also crashing here:

usbredirserver 0c76:1607
usbredirparser info: Peer version: qemu usb-redir guest 0.15.0
Bus error (core dumped)

qemu -cdrom xxx.iso -readconfig /usr/local/share/doc/qemu/docs/ich9-ehci-

Maybe Hans de Goede should do some testing with FreeBSD-current ?

I just submitted the patch for FreeBSD-current that implements 
libusb_get_device_speed().
