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 3-1: pl2303 converter now attached to ttyUSB0
|
||
|
|
usb 5-2: FTDI USB Serial Device converter now attached to ttyUSB1
|
||
|
|
usb 1-7.2: generic converter now attached to ttyUSB2
|
||
|
|
|
||
|
|
|

|
|
Install the latest firmware image:
|
||
|
|
|

|
