Extracting internal storage from a non-bootable TF101. topic

Hello, as some of you might have noticed in my previous posts around xda, my tf101 is royally screwed up. I'm stuck in a permanent recovery bootloop, and I can't be saved by my PC. the only concern i have now, is just trying to get the files I had on its internal sdcard. could I somehow put the motherboard into a TF101 with a working USB port, or can I somehow connect a torn USB cable to certain pins on the motherboard to detect it? (my friend once said something about UART connections). I only want to get the files. doing things with software seems out of the question now. hardware tricks might be the only viable option for me... I would really appreciate any kind of answer. whether it's a "that's impossible" answer or otherwise. either way, I'm probably just going to be leaving xda forever. so like I said, does anyone in the vast, knowledge a filled xda community have any ideas?
