WHAT filters? Either connect the lines straight, or use specific USB protection device (ST has such).
Any additional RC may delay/attenuate the communication and render it useless, esp. on 12 Mbit/s and higher! Do you compile for proper board version? There is huge difference between 107 and 103 boards (called -C and -B or -E)
