I want to compare data between affymetrix chips of human HuEx-1_0-st-v2
and mouse MoGene-1_0-st-v1
. First step is I need to map probe id between these 2 arrays. Any suggestions?

I don't think you can compare probe IDs against two different arrays from two different species. What you can do thought is to use BioMart to find the correspondence between the human probe IDs (FILTERS) and HGNC genes (ATTRIBUTES) and then their mouse orthologues (ATTRIBUTES). And you can do the same for mouse: find the MGI symbols (ATTRIBUTES) mapped to the mogene array (FILTERS) and get the human orthologues if you wish.
From the page http://www.affymetrix.com/support/technical/comparison_spreadsheets.affx#1_3
You could find there are comparisons of across species between arrays.
Within species between arrays: http://www.affymetrix.com/support/technical/comparison_spreadsheets.affx#1_2
These comparisons were generated by Affymetrix, but they are not generating any more. What I need is the comparison between Human Exon 1.0 ST Array and Mouse Gene 1.0 ST, which is not there.
Therefore, I am looking for any open sources tools to match probe ids of these 2 arrays. Any suggestions?

Details on what these ids are would help you get a more relevant answer. Like, are they numbers? Where are they suited? In what format ate they stored? The more details, the more relevant our answers can be!
The probe id for these 2 arrays are numbers.
Human one is :
Mouse one is:
