Retro Fighters Hunter - wrong USB firmware

Hello,

I'm using Retro Fighters Hunter as my main Xbox Classic controller and today I've decided to update firmware. Unfortunately... somehow I've done a dumb thing and by mistake used Xbox dongle firmware to update USB dongle firmware. Please don't ask how I've do that - xbox dongle update passed without any problems and somehow I've entered again the same folder to update USB dongle. Have a few Retro Fighters controllers, so it's not my first update :V

Yes I know - I'm dumb as f*ck and now my USB dongle is bricked. Is there any way to "unbrick" the USB or it's permanently "destroyed"? Does anyone encountered similar problem? :/
