Thank youvery much.
I followed the instructions to the point where ibm_capsense_usb_util.exe recognized the keyboard, but when I set the threshold below 120, it still could not recognize the keypress.
I tried to write again with QMK, but in QMK Configurator I mistakenly wrote in a hex file created by xwhatsit/brand_new_model_f/f77/universal, and my PC stopped recognizing atmega32u2.
Is this xwhatsit unrecoverable in this case?
