I have installed a Sandisk

Question

I have installed a Sandisk ImageMate USB 2.0 SDDR 99 V4 5-in-1 reader on a Win2000 system. The system recognised it and added it to the list of drives but when I attempt to restart and update the system it won't boot past the Intel m/board splash screen. If I remove the reader the system then boots normally. The m/board only has USB 1.
