[ubuntu] PCI tuner card passthrough

I am attempting to detach my TV Tuner card as a prelude to setting up passthrough from Host to KVM Guest
COMMAND
~$ discover --vendor-id --model-id pci | uniq
OUTPUT
1131 7160 Philips Semiconductors SAA7160
COMMAND
$ sudo virsh nodedev-dettach pci_1131_7160
OUTPUT
error: Could not find matching device 'pci_1131_7160'
error: Node device not found
Any ideas as to why this PCI can not be found?
