Trouble with USB High Sierra Patcher Tool

I have a Mac 5,5 2009 MacBook Pro. It has a Core 2 Duo processor, 8 GB of RAM and a 250 GB SSD. I have El Capitan running on it which runs out this fall. I downloaded the patcher tool from dosdude1's website. I download the High Sierra file via the menu to desktop. I've tried two different USB drives and a 2.5" notebook drive to create a bootable installer. Every time I select the USB or hard drive in to boot from in the Recovery menu (press option after hitting the Power button), I get a circle with slash through it. I don't understand why it's not recognizing the USB drive. I've also tried creating the USB installer from Carbon Copy Cloner and Create Disk Installer including the dosdude1 patcher tool but to no avail. Does anyone know a fix or a workaround? Please help!

Don’t use the recovery to boot.

Reboot and hold down the OPTION key.

If the drive is compatible for booting (not all USB drives are) and you used dosdude1’s patcher to create the installer, then it should work just fine.
 
I had to use a fresh SanDisk USB to get the installer to take. Once that was done, it recognized the stick and went through the operations properly. Thanks.
