Description of problem:
fail to do USB redirection to VM launching on rhel7 host with gray 'USB device selection' button in virt-viewer client when remote pass-through usb stick from rhel6.5 machine with cirrus vga specified in qemu-kvm cmdline.
BTW, 
1.If use the qxl vga cann't hit such issue which redirect the usb device successfully.
2.The opposite testing work, if redirect the usb stick from rhel7 machine to a VM running on a rhel6.5 host which works well.

Version-Release number of selected component (if applicable):
host(launch VM) info:
3.10.0-121.el7.x86_64
qemu-kvm-1.5.3-60.el7.x86_64
usbredir-0.6-7.el7.x86_64
usbredir-server-0.6-7.el7.x86_64
spice-server-0.12.4-5.el7.x86_64

rhel7 kerenl-3.10.0-121.el7.x86_64

usb-host(run virt-viewer client) info:
rhel6.5: kernel-2.6.32-448.el6.x86_64
virt-viewer-0.5.6-8.el6.x86_64
spice-client-0.8.2-15.el6.x86_64

usb device info:
USB 2.0 stick
Bus 002 Device 004: ID 0951:1642 Kingston Technology DT101 G2

How reproducible:
100%

Steps to Reproduce:
1.launch a rhel7 VM on rhel7 host with usb-redir and cirrus vga specified.
e.g:# /usr/libexec/qemu-kvm -M pc -cpu SandyBridge -enable-kvm -m 2048 -smp 2,sockets=2,cores=1,threads=1 -no-kvm-pit-reinjection...-spice disable-ticketing,port=5933 -vga cirrus -device usb-ehci,id=ehci0,bus=pci.0,addr=0x7 -chardev spicevmc,name=usbredir,id=usbredirchardev1 -device usb-redir,chardev=usbredirchardev1,id=usbredirdev1,bus=ehci0.0,debug=3
2.insert the USB 2.0 stick to a rhel6.5 usb-host.
3.run the virt-viewer client on the rhel6.5 usb-host.
# remote-viewer spice://$rhel7_host_addr:$port
4.select the redirected USB stick device via "'File' menu
--- 'USB device selection'" in the virt-viewer client. 

Actual results:
after step 4, fail to select the redirected USB stick device via "'File' menu

I can reproduce this bug with:
virt-viewer-0.5.6-10.el6.x86_64

Steps:
1.On rhel7 host,prepare a spice+cirrus rhel7 guest,configure usb redirection.
2.On rhel6 host,launch remote-viewer to connect rhel7 guest configured on step1.
# remote-viewer spice://$rhel7_host_addr:$port
3.select the redirected USB stick device via "File"->"USB device selection" in the virt-viewer client,the 'USB device selection' button was grayed out.

3.select the redirected USB stick device via "File"->"USB device selection" in the virt-viewer client,the 'USB device selection' button was grayed out.

Tested with:
virt-viewer-0.6.0-4.el6.x86_64
