Hello, there
I have designed and assembled customized PCB board of Teensy4.1.
Currently, I am testing with it, but the board is not connected with PC at all.
I checked device manager of PC, but there is no any changes when I plug the USB cable.
All peripherals are normal : assembly, oscillator, DCDC_LP is 1.2V, USB Cable is normal.
When I press PROGRAM MODE BUTTON 13~17s, the LED of bootloader is bright.
But, the custom board is not connected with PC at all.
If anyone have experience in this, please help me.
Thank you
