[Bug 787091] Re: Unable to use USB device in KVM quest

[Royston Carter]

At Serge's request.
I have run a fresh set of tests with this issue. I rebooted the host with the usb canon mp510 printer attached and turned on. At 11:25am I started the Windows XP VM with virt-manager. The attached tar file contains the outputs of:

dmesg
/usr/log/libvirt/qemu/VM.log
lsusb
ls -l /dev/bus/usb/001/002
short extract of /var/log/kern.log,messages, debug, daemon.log

/tmp# for i in `pidof kvm`; do    echo $i >> statusinfo;    cat
/proc/$i/status >> statusinfo;    echo >> statusinfo; done


/tmp# strace -f -ooutout2 qemu -usb -usbdevice tablet -vnc :2 -vga cirrus -usbdevice host:04a9:1717
usb_create: no bus specified, using "usb.0" for "usb-host"
husb: open device 1.2
husb: config #1 need -1
husb: 3 interfaces claimed for configuration 1
husb: grabbed usb device 1.2
/tmp#
