Re: [gentoo-user] TUSB3410 on 3.0.6 kernel

[Érico Porto]

A guy replied this in the e2e ti`s community :
*
n the directory /etc/udev/rules.d/ create a file with the name
026_ti_usb_3410.rules *

*Copy to into this file the following lines*
* *

*#TI USB 3410*
* *

*SUBSYSTEM=="usb_device" ACTION=="add"
SYSFS{idVendor}=="0451",SYSFS{idProduct}=="3410" \*
* *

*SYSFS{bNumConfigurations}=="2" \*
* *

*SYSFS{bConfigurationValue}=="1" \*
* *

*RUN+="/bin/sh -c 'echo 2 > /sys%p/device/bConfigurationValue'"*
* *

* *
* *

*NOTE: Please replace the VID/PID with your device’s VID/PID.*
* *

* *
* *

* *
* *

*At the time you finish this process reboot your system and connect your
device and you must be able to see the node in /dev/ttyUSB0 as your serial
port.*


I will try this when I get home.
