vuescan won't start

["Richard Carter" <carter.r.a.l@gmail.com>]

Hi Folks,  

I'm running debian 4.0 (etch) on a PC with an amd64 processor.  

I downloaded vuesca84.tgz and expanded it to /home/robin/vuesca84 which now includes an executable file vuescan.  When I enter "vuescan", as either robin or as su, I get:

vuescan: error while loading shared libraries: libusb-0.1.so.4: cannot open shared object file: No such file or directory

when I enter "locate libusb-0.1.so.4" I get:

/lib/libusb-0.1.so.4
/lib/libusb-0.1.so.4.4.4

How can I get vuescan to start?
