This is from some notes I have, but
first find your device in lspci -n output

Say I had a device as follows:
00:01.0 0604: 8086:29a1 (rev 02)

I'd try:
echo "8086 29a1" > /sys/bus/pci/drivers/pci-stub/new_id
echo "0000:00:01.0" > /sys/bus/pci/devices/0000:00:01.0/driver/unbind
echo "0000:00:01.0" > /sys/bus/pci/drivers/pci-stub/bind
