Unofficial USB peripherals and CFW 3.55, working?

Hi, I have one of those Xbox360 controller to PS3 adapter to plug my Xbox360 wired controller as my main controller.

I have not found anywhere the information regarding if the protections disabling the use of unofficial USB peripherals on 3.55 could have been disabled/removed in some CFW.

Is it the case? If not is there a work around? I like so much more playing with a Xbox360 controller than the PS3 ones. I wouldn't want to lose this possibility.

Thanks!

Well I went ahead and installed Kneaw 3.55 CFW and my Xbox360 controller to PS3 adaptor still works.
