drupal_add_js conflict with view_slideshow module

i created a blank module called customjs and only add a line

drupal_add_js('misc/jquery.js');

and views_slideshow module is also installed, but there are a errors after i added the code:

ReferenceError: jQuery is not defined

Drupal.theme.prototype.viewsSlideshowControlsPause = function () {

views_...?man44s（123 行）

TypeError: Drupal.theme is undefined
Drupal.theme.prototype.viewsSlideshowControlsPause = function () {

what the problems? anyone knows? thanks
