XEBRA have always been funny when it comes to controller configuration. I'm using a EAXUS PS USB adapter with my original PS2 controller and I always had to use the Digital option in XEBRA because the other options didn't work. XEBRA is an amazing PS emulator but broken controller configuration is not good at all as it's one of the most important aspects for playing your games. And as you say other emulators doesn't have this issue at all, I'm currently on ePSXe and my analog sticks works just fine. I'm not even sure if Dr.Hell comes to this forum or if he/she speaks English as the main website is in Japanese and the forum as well. This is a problem and a big turn down for me, not to be able to communicate with the author of an emulator/plugin and just waiting for issues to randomly be fixed.
