usb 1-3.4: New USB device strings: Mfr=1, Product=2, SerialNumber=3 In my case my vendor and product id were 10c4 and ea60 respectively ( dmesg told me so) usb 1-3.4: New USB device found, idVendor=10c4, idProduct=ea60 CP210x UART Bridge / myAVR mySmartUSB lightĪfter some searching I found advice that recommended a forceful serial mount by writing the vendor and product id to /sys/bus/usb-serial/drivers/ftdi_sio/new_id. When I first try to establish connection to the serial device I was surprised that Ubuntu did not mount the serial device at all (as in there was no /dev/ttyUSB0), even though lsusb lists the device Bus 001 Device 026: ID 10c4:ea60 Cygnal Integrated Products, Inc.
