Configure usb scanner

Hi, I have the following problems: I installed an Acer/Benq 3300 usb scanner that works fine. The problem is that the scanner is only recognized by the system after I run the script "acerfirm u176v042.bin" that update the firmware of scanner. Every time I was turn on my computer I need to do that. How can I automatically do that on the startup? Thanks Thadeu
