Driver problem with USB TA

I have W2K SP4 on my laptop. I have a Belkin USB 2 cardbus adapter. I am
trying to install a USB ISDN TA connecting to the USB2 cardbus adapter. All
the USB drivers and devices are working OK.
When I plug the TA into the adapter I get the "Found New Hardware" box.
Fine. I then tell the New Hardware Wizard to search for the driver. It will
NOT allow me to use the W2000 driver from the installation CD. It keeps
telling me there is a "closer match" with a driver called oem2.inf in the
\WINNT\ folder. If I allow it to use this driver, it then tells me there is
an error and it can't install the device! How do I get round this? is there
any way to FORCE the wizard to use the driver from the CD?

Thanks
