Why does a new VM not boot from the same USB stick that I installed all of my organization's machines?

All of my org's machines have been installed from the same USB stick. I keep building machines from it daily. But when I add that as a USB device to a Proxmox guest, it refuses to boot from it. I select it as a boot device in EFI but it blows straight to PXE. I put this device 1st, but it blows straight to PXE. What does Proxmox need to boot from the stick that all of our machines happily boot from?
