This is the
pSX Emulator section of the forum, lokocruel - pSX is a a specific Playstation Emulator (probably the best yet) and this isn't the section for PSEmulator. However, maybe you should try it - it seems generally to deal with controllers better than other emulators.
For your specific query, maybe you should try the section for
plugins based on the PSEmulator system, or if you're actually using pSEmulator itself, the
Misc PSX Discussion section.
However, it's not very clear just what your problem is: presumably you're trying to use a Playstation 2 controller with something called "adapt usb portal?" You should explain (in the relevant section) just what the problem with this is, and what an "adapt usb portal" is.
