Not showing multiple browsers for single user

Hello Piwik community!

I am tracking visits by setting my own UserId:
_paq.push([‘setUserId’, qs[“user_param”]]);

This Visitorr Profile screenshot shows 2 visits by the same user, the first visit I used Chrome, the 2nd IE:

My problem is: I don’t know the user accessed my site with Chrome
My question is: Since I’m setting the UserId myself, is it possible to show all the browsers userd by a single user?

I’m using Piwik 3.0.1 on Windows 7 (developing under localhost using PHPStorm).

Thanks for your thoughts!
