I received a Form1+ from a coworker and in updating the printer to the latest firmware and moving, I have found that the printer no longer is being recognized by my PC. I have tried connecting it to different windows machines and a mac with no luck.
I investigated and found that the D+ pin is shorted to ground on my USB connector. I have been probing around and have a suspicion that I somehow damaged U12 on the board. I couldn’t read the top of my part but i did find a nice picture on the OpenFL github that shows the text. Can any of you with a Form 1+ take a picture of your board or let me know if the text on the top of U12 is the same as what is on the picture below?
I believe it is the ESD protection for the USB port and am trying to determine what the part number is. I believe it to be a TI TPDE001 part. Any help would be appreciated.
