Peripheral Control Policy for custom devices

Hi, I have setup a peripheral control policy and set to block MTP/PTP. With this policy, it disables my Canon MBP643 and I went looking at the exemptions. I've added "CANON_MFNP&MF642C" which was detected. However, when I retinstall the printer driver another message pops up, saying \ROOT\IMAGE\0000 is blocked by your administrator. This "device" however, is not detected.

How can I add this to the exemptions?

At this point in time, I am only able to get my scanner/printer working if i set Allow to MTP/PTP.
