: You're giving me credit where it isn't due I just use the services of SpamCop for my email. On the other hand, you might have heard of me in the ShareWare world --- but that was a long time ago, now...

Geez....don't I feel like a dope! LOL!

Anyway, we have a problem here, Houston. You are using an ACPI "HAL" for on laptop for good reason - power management. Laptop power management is a critical isse, obviously. Unfortunately, that ACPI HAL is causing massive IRQ-sharing, which USB 1.1 ports do not like. I'm not sure that we could undo the sharing anyway because moden laptops have the USB, VAG and sound subsystems hard-wired together.

I would suggest a "ROM" (BIOS) update from Compaq. I would also recommend contacting them about this. They may be aware of a problem and have a fix for you. Tell them USBMan sent you. ;-)

: : Let me start by saying THANKS, Bob. I am a user of your services and recommend SPAMCOP regularly. You provide a wonderful and necessary service. Kudos!

: : Laptops can be a pain because the USB subsection is usually hard-wired to the VGA and sound subsystems. This sometimes causes IRQ-sharing which USB 1.0 controllers don't like. Open System Information (MSINFO32.EXE) and navigate to Hardware Resources > IRQs. Click anywhere in the right pane and then press CTRL-A and then CTRL-C. You have copied that data to the clipboard. Paste that data in a reply here.

: : Once I have that data, I can formulate an attack plan.

: : : I purchased a CannonScan n670u to use on the road with my Compaq (XP personal) notebook. The major attraction of the Cannon scanner was its portability --- it is small, has a lock down cover, and is powered thru the USB port.

: : : The scanner works fine with my (older) Compaq desktop.

: : : During install on the notebook, it was recognized correctly when I booted with it attached, and loaded all the software.

: : : When I try to use it, I'm getting the message now that it is not attached. I strongly suspect that the feature of being powered by the USB port & using it with a notebook may be the root of the problem (but the scanner sure looks like it was meant to be part of a traveling pair).

: : : I've been unable to find any information at all about the compatability of this particular pair.

: : : Anyone have any information on this combination?

: : : Thank you.
