Thanks for your help but actually I don't really know where to look for the driver.

But I tried to run the dependency walker on my program (myQtProgram.exe) and here is what it says:
EFSADU.DLL: Error opening file, impossible to find the file
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.

Then I tried to look for EFSADU.DLL on my computer but I don't have it.
