Hi guys

I intended to not allow redirecting some of my usb devices(HID) to the guest, i thought https://www.spice-space.org/usbredir.html
could help on this.

My host has below usb devices

lizj at FNSTPC:~/workspace/vgt/virt-viewer/src$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 006: ID 04d8:0b2a Microchip Technology, Inc.
Bus 001 Device 021: ID 046d:c534 Logitech, Inc. Unifying Receiver
Bus 001 Device 004: ID 0424:2137 Standard Microsystems Corp.
Bus 001 Device 003: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS
802.11n WLAN Adapter
Bus 001 Device 002: ID 0bda:8771 Realtek Semiconductor Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

$ remote-viewer
--spice-usbredir-auto-redirect-filter="-1,0x0bda,-1,-1,0" --spice-debug
spice://localhost:5900

For testing, i just want to hide produce id 0x0bda from remote-viewer
with above command line. But acutally

i am still able to redirec both Realtek device to the guest through
remote-viewer.

So is there something with my usage ? Feel free to let me know if there
is something wrong.

The auto-redirect-filter only works for auto-redirected USB devices.
When a user is choosing a device from the menu, the filter does not apply.

Thanks
