hi,all
if user has several usb, and plug them at the same time when using
spice-client. all usb devices will be present in guestVM.
i want to know   if i can control which usb device can be present in
guestVM?

Yes, you can, using filter string. There is actually a default filter
string in the client that prevents auto-redirection of USB HID devices
(keyboard and mouse).

Filter string can be set on client side (this one controls
auto-redirection) or on server-side (this enforces that disabled devices
can not be redirected to the guest). The basic format is
"class,vendor,device,revision,enable" with "-1" as a wildcard, so when
you launch client with:
--spice-usbredir-auto-redirect-filter="-1,-1,-1,-1,0"
no USB device will be auto-redirected. If you specifiy "-1,-1,-1,-1,0|
8,-1,-1,-1,1", only USB mass storage devices will be auto-redirected.

The full documentation of filter string used to be on Hans's site:
http://people.fedoraproject.org/~jwrdegoede/spice-reference/SpiceUsbDeviceManager.html#SpiceUsbDeviceManager--auto-connect-filter
but it seems to be gone now. Hans, where does it reside now, please?

I removed it while cleaning up my fedorapeople web-space, but we still
don't have an official place for it AFAIK, so I've put it back.

So now the above link should work again :)

Regards,

Hans
