You can just use variables from an outer scope in your callback: 
my $source = “/mnt/usbdisk”;

sub Recursive
{
    my $msg = $source;
    ...
{

This is the general way to handle such problems in Perl. You can abstact that away with closures: 
sub myfind {
   my ($code, @args) = @_;
   find(sub { $code->(@args)})
}

Now you can call 

myfind \&Recursive, $source;

And have the argument $source passed through to sub Recursive. But most likely you can solve your problem with outer lexical variables in the first place.
