Problem using various USB adapters

[zahhhkinnn]

Hi, i have  a problem using 4 usb adapters (2 snes    and 2 nintendo 64 ), im planing on having all connected at the same time, and they all work fine on windows (ive checked on devices and printers and all the inputs are registered), the problem is when im setting the keys on the emulators (zsnes and project64), for project 64 theres no problem, for zsnes it only lets me set the player 1, if i want to set player 2 i have to unplug the two n64 adapters and it works but when i plug the n64 adapters back both snes adapters stop working, i know this is a problem of zsnes because i use snes9x and i can set both players ok, ive installed again zsnes and i have the same result, please help me i dont know what to do, also, this same setup worked on another pc i didnt have any issue :\. thanks you for your help.
