XP on Dell won't boot if Epson CX6600 is turned on.

I have a customer who has a weird problem.

The computer is a Dell 4600, running XP Home.  The printer (a brand new Epson All-in-One CX6600) works fine once the operating system is loaded.  Scans fine, prints great, etc.  It's USB 2.0.

With the printer plugged into the USB port on the back of the computer (and turned on), the machine will not boot to Windows.  Just before the big Windows XP splash-screen it will hang with a blinking cursor in the top left-hand side of the screen and just sit there.  If you hit control-alt-delete, the machine reboots and goes right back to the same spot.  If you do this several times, eventually you will get a DELL screen that says something about "Previous attempts at rebooting this system have failed..." and then mentions a "Checkpoint [USBd]".

The funniest thing is, when the computer hangs at the aformentioned blinking cursor, all you have to do is turn off the printer (or unplug the USB cable) and the computer's boot process immediately jumps to the Windows XP splash screen and continues to boot normally.  Then, you can immediately turn the printer back on (or plug in the USB cable) and everything is perfect!

I know this is isn't a really serious issue, but this is really annoying to the customer (and would be to me, too), and there is no mention of this problem anywhere on the internet.  I've tried, of course, to speak with Dell support, but since moving their support across the pond they just hear the word "Epson" and immediately say that it's a printer problem.  Personally, I don't think that it's a hardware issue, and am more inclined to think that it's a service or driver that's trying to load, apparently unsucessfully.

I need an extra pair of expert eyes on this thing, pronto.  Can anyone help?

    Hi.  Have you checked the boot order in the BIOS?
    Make sure your hard drive is listed before a removable or USB for boot order.  If you want to be sure, and if you need the ability to boot from CD, change the order to CD ROM, HDD, and then something else.

    Solved this problem yesterday, thanks to the tip from gpriceee.

    There is an obscure setting in the Dell CMOS, not under boot settings (as one would expect), but under the integrated peripherals.  It was called USB emulation (or something similar).  Setting this to "no boot" worked like a charm.  Customer is happy, and I'm very happy.
