XP home edition. I installed the flash driver and it’s been operating fine –

I’m afraid you probably answered your own question. Installing SP1 on top of
SP2 should not work. To be honest, I’m surprised that installing SP1 on top of
SP2 didn’t give you some kind of error message.
But if it succeeded … well, that’s just not good.

First let’s be clear. Service packs are cumulative. If you install SP2 you
don’t need to install SP1 … everything in SP1 is already in SP2 (unless of
course it was something that needed to be fixed by SP2).
And if you don’t already have SP1, you don’t need to install it before SP2
… just install SP2.
As I said, installing SP1 on top of SP2, if it actually succeeds, can only
cause problems, in my opinion. I’d certainly suspect it with the symptoms
you’re seeing on your USB drive.
If you’re trying to revert from having installed SP2, you need to use
uninstall, if you had SP2 create an uninstall directory when it was installed.
If you didn’t, you’ll need to reinstall Windows XP to revert.
If you’re just trying to fix a problem you believe has been caused by SP2,
then I’d start by running the system file checker (See What is the System
File Checker, and how do I run it?).
But I will warn you. If SP2 caused you problems, there are many possible
reasons, most of which are in your control. Making sure you’re spyware-free
before you install it is perhaps the most important, so if you do start over,
make sure your machine is as clean as possible and follow the instructions in

But you don’t need to install SP1 if you’re going to install SP2.
