USB not working- what can i do?

Post by Chris72160 »

Hello,

i am building my second x0xb0x and i found out, that the USB-port is not working, although the USB driver is properly installed.

Because my first x0xb0x is actually not here, i can`t compare any values on the board.

May anyone can tell me what i can check with the oscilloscope? How can i check the ceramic resonator and the FTDI itself?
