USB Hub and media reader prevents full system power off

I am using a Belkin 15 in 1 card reader which also has an integrated 3 port USB 2 hub

<details @ http://catalog.belkin.com/IWCatProductPage.process?Merchant_Id=&Section_Id=200597&pcount=&Product_Id=193438&Section.Section_Path=%2FROOT%2FUSB%2FMediaReaders%2F >

I am running Windows Xp Pro with SP2. I have several USB devices connected to this computer and have not had any problems. I have tryed using onboard usb ports to connect this device and I have tryed using a USB 2.0 pci expansion card.

This device has its own power unit.

When this device is plugged into this machine, it prevents the machine from completely shutting down. The computer (when shutdown is selected) will power off and the HDD, PSU and CPU will turn off, however the computers lights on the front of the machine will remain on. To turn the machine back on again, I need to pull either the power out of the USB hub or pull the power out of the back of the computer.

I have been through the bios and power management settings and have tryed all the settings I can imagine. I am pulling my hair out. I have even gone as far as to replace the unit with a new one. I have been told that the unit is in-compatible with my motherboard. Understanding why is beyond my knowledge field.

PLEASE PLEASE PLEASE PLEASE PLEASE

Can someone help me .. I am willing to try anything to get this going and it is driving me nuts. The manufacturer has told me that they will not authorise for the product to be refunded and I will have to simply put up with the fact that I bought something which is in-compatible with my computer.

ANY HELP APPRECIATED .. this will be a tough one to solve .. if it can be solved.

Not sure, but you can try putting a powered hub between the media reader.
Make sure you have installed all the newest drivers for you mainboard. What could also help is to remove all USB devices from the system except the keyboard/mouse, then uninstall all USB devices from your device manager. Windows should then install it's own drivers. Once they are installed back on, you can replace the USB peripherals one by one.

Does it act the same if you have a card in the slot and if not? Can you also run msconfig and post the entries for "services" and "startup" programs here?

Thanx
