T400 with right USB problem

I have a problem with the right side USB on my T400, obviously a pain the butt


so in the service manual section 1180 covers the disection to get at the USB sub assembly, almost literally have to take the machine completly apart


I have the PCMCIA/Express Card version which is adequate for my needs. I have a USB 3.0 card installed in the top slot.


no pain, no gain, so is the USB sub assembly fixable, USB shows a device error suggesting a signal problem and I wonder if there is a problem with the logic board as opposed to a damaged port



I own: T400 T500 X220 X230 all running Windows 10 Professional

And we're back...
