CSL pedals with load cell brake firmware update

Hey guys, I've installed the load cell kit to the CSL pedals and connected in the configuration for using the original brake pedal as clutch. So all three pedals connected to each other per instructions with only the RJ45 going to the wheel base.

I've mounted the shit out of it and now realized I need to connect the pedals via USB to update...independently of wheelbase and steering wheel...and I can't access the USB anymore unless I undo some of the annoying mounting.

Could I connect the RJ45 (that would go to the wheelbase) to an adapter that takes it via USB to the PC and then update the firmware this way?

Just trying to see if I really must undo the damn mounting. Kinda annoying that I can update wheel, motor, and wheelbase with the same cable, but not the pedals...

Thanks in advance!
