Oh, dear. You might have put the "wrong" version of Pike's boot.efi onto your USB.Not sure what the update was--but I hate it.
On my usb--the boot.efi file was about 313kb (which was same size/date as another copy I have saved on another/newer Mac).
But--following your suggestion/video above--I copy/pasted boot.efi from my original install (saved on different computer) into my boot usb in 2 locations:
a) System/Library/Core Services
b) usr/standalone/i386
Then, ejected usb, plugged it into Mac Pro 2,1.
Boot--white apple on black screen--"progress bar" frozen ~1 inch x 20 minutes.
Other suggestions?
Pike's version 2.x releases were targeted at Yosemite.
Pike's version 3.x releases were targeted at El Capitan.
I'm not sure, v3.1 might be compatible with Yosemite, I've never tried it....

Okay, you mention another machine....Power--bong--alt--2 disks (one main hard drive, one recovery 10.10)--no usb icon anywhere.
Click recovery 10.10--gray screen.......that never ends
Thoughts?
Do I have to remake the USB installer by following complete instructions?
I'm assuming that is a Mac as well.
Do you have a FireWire cable, and ports on your other Mac? If you do you can put the MacPro into target disk mode.
Connect the two machines together with FireWire, reboot MacPro, bong, hold Apple and T.
In target disk mode your other machine should see the MacPro disks as attached disks.
Copy the boot.efi files using your other Mac

Do you have an external HDD caddie? If so pull the MacPro HDD and attach it to the other machine...Oh, dear. You might have put the "wrong" version of Pike's boot.efi onto your USB.

OR
Yes, you could rebuild your USB stick. Before you do that, try connecting that to your other machine, and use the Terminal to run the bless command. Bless the USB stick properly and it will probably then show up as bootable
