How do you think a do while loop works in C?
DriverFound = FALSE;
do {
;
} while (DriverFound);
Is not an infinite loop? It just runs one time.
The code is looping as long as Start() is called as calling Start() could cause
other drivers Supported() to start returning TRUE, so you have to recheck the
set after calling Start().
