There are no BAR resources for this device:

Vector table: BAR=4 offset=00000000
PBA: BAR=4 offset=00001000
There is no BAR4 for either the vector table or the PBA, the device is broken. Maybe check dmesg for resource allocation errors. Note that a device ID of 0000 is also reported for this device. Does this device provide any useful function in the host outside of vfio?
