X1 Tablet Gen 3 Keyboard connector

[devicemodder]

Was wondering, since the X1 tablet Gen 3 uses USB for the keyboard on the POGO pins, can i use those to run other USB devices, like a flash drive?

Can't find much info on that bit online, but found lots of info for converting the Keyboards to USB. I tried wiring up a USB port following

but the 5V pin reads at around3V or so.

I have the medical case on my X1 tablet and would love to have an extra 2.0 port as part of the case.

Update: If i connect a 10K resistor between ground/pin1 and pin5 (NC) i get a USB ding and then i see voltage on the 5V pin, but it drops to 2-3V when i plug in a flash drive and windows gives me a "USB device not recognized". but... if i supply external 5V to the flash drive, with the power disconnected from the tablets 5v pin, the tablet recognized and mounts the flash drive. there's gotta be a way to keep the USB pin voltage stable. unless it's going overcurrent trying to run a flash drive...

Following as planning to do the same. Did you have any success?
p.s. I think the pinout you showed in the figure has data+ and data- reversed, which could cause the "not recognized" issue. check this out: https://www.reddit.com/r/thinkpad/comme ... t_3rd_gen/
