Have you tried a BIOS update?
What type of power supply do you have? Is it up to the task at hand? I would recommend a name-brand 400W PSU for that system.
: Once again, thanks.
: Unfortunately I've already tried that option since the Belkin adapter which I installed is USB 2.0. The Belkin part number is F5U220 (as recommended on your website). Exactly the same "shut-down" phenomenon occurs.
: : It's possible, but no guarantees. I would prefer to see you buy a USB 2.0 adapter.

: : : Thanks for the quick response Bill.
: : : I like your idea regarding the reader drawing too much power. However, the same problem happens with two different devices. One is the card reader and the other is a digital camera (essentially just another card reader).
: : : If it is a power issue, would installing a separate USB hub be a possible way to solve the issue? I would be willing to give it a try ...
: : : Thanks again.

: : : : Disabling ACPI in SMP setups is problematic. The secret to stable dual-processor setups is to set the OS to "Non-PnP" in BIOS setup before installing. You can try changing the HAL in Device Manager, but I think that the reader is just drawing too much power on replugging. It's another example of another poorly designed reader - and there are many.

: : : : : I can insert a compact flash reader into the USB and everything functions normally. I can also stop the reader (with W2K) and then disconnect it. However, when I re-connect the reader the system crashes and restarts (i.e. a complete power-down of the computer). The system log states that a bugcheck dump was written but I'm not an expert in using those Windows dumps.
: : : : : I purchased a new Belkin USB controller, thinking that the VIA controller could be the problem, but the same thing happens.
: : : : : I am running the ACPI HAL (instead of the standard HAL) and have noticed from other posts and tips that this could be the problem due to IRQ conflicts. However, since the system works fine before I disconnect the USB device I am thinking that the IRQ's might be o.k..
: : : : : Just wondering whether anyone had any ideas?
: : : : : Thanks.
