I know I am new to GP, but I am really puzzled. I have been able to set
up many GPO to control how the users can use their PCs very
successfully, but am stymied about this one issue. USB Storage use!
I have been trying to shut down USB Storage use for some time with GP,
but to no avail. I have created a No USB GPO with the .adm templates
from several downloads, but whenever I attach it to a OU in the Active
Directory, it does NOT prevent the USB sticks from working! If I go to
the PC and edit the Registry manually, I can shut down its use. Not
what I want to do. Attached are the adm file and GPO that I have
created. Can you simply tell me where my logic is in error? Hopefully,
it is obvious to someone else, but I am going blind.
Thanks for any help,
Jim

Default ADM Templates / Disable USB

I will assume your machines are capable of having the ADM templates applied. With that said, read this support KB from Microsoft and ensure you have verified you have things setup as suggested.

Recommendations for managing Group Policy administrative template (.adm) files - ADM template article

What your trying to accomplish is not easy to manage, audit, or verify that it has applied successfully. Disabling USBs is one thing, but tracking whose plugging in the devices is quite another.

Even with Windows 7 and newer group policy in Windows 2008 R2 this task is better left to third party tools. Microsoft does not have any interface to easily control and manage this option.
