Where is your driver sending DEBUG() prints?
You can add this to the edk2 build command --report-file=build.og
The build.log will tell you what library instances are getting used by your
driver.

Subversion Kills Productivity. Get off Subversion & Make the Move to Perforce.
With Perforce, you get hassle-free workflows. Merge that actually works.
Faster operations. Version large binaries. Built-in WAN optimization and the
freedom to use Git, Perforce or both. Make the move to Perforce.
