Lost Communications with Pedals

in Pedals
My clubsport dd plus and clubsport v3 Pedals arrived last week. I made the mistake of plugging in the usb and rj12 cable together for about 10 minutes. I realized my mistake and quickly fixed it. I Raced all week on Iracing no problem, then one race all of a sudden, the pedals became disconnected from, and they wouldn't work. I exited iracing and pulled up the fanatec control panel and it would not recognize the pedals. When i would press the gas brake or clutch NOTHING!
I unintalled and reinstalled the fanatec driver, then it would recognize the pedals and it seems to working fine now. Would this be just something freakish or is this a problem of my mistake???

When both are connected, supposedly will blow the pedal control board, so if its still working you may have dodged a bullet - not sure why un/reinstall of driver would fix it tho
thanks!! cant get any help from fanatec
