To make sure that the SAM7 interface will be recognized
by the Linux Kernel please add the following line to
/etc/modprobe.conf.local (or /etc/modprobe.conf if this
file doesnt exist):
options usbserial vendor=0x03EB product=0x6124
(Re)Plug your device to make sure it will be detected properly.
Find out which serial port its connected to (see last line
- it's ttyUSB2 in this particular case):
dmesg | grep ttyUSB

usb 5-2: FTDI USB Serial Device converter now attached to ttyUSB1
usb 1-7.2: generic converter now attached to ttyUSB2
