Sorry, that's not possible. 2.6.21 doesn't include USB Persist
support. Nor does 2.6.22.
There were some experimental patches with early versions of USB Persist
for those kernels. They are different from what eventually went into
2.6.23.

USB Persist was never meant to allow you to detach and reattach a
device while the computer is suspended; it was meant to deal with
hibernation. So what you observed is the correct behavior, not a bug.
Detaching and reattaching a device while the computer is suspended
should result in exactly the same behavior as detaching and reattaching
the device while the computer is awake.
If you try doing the same thing but with the computer in hibernation
instead of suspended, you may find it more in line with what you
expect.
