I got my device working with intrepid!

Output of lsusb:
Bus 003 Device 004: ID 0451:3410 Texas Instruments, Inc. TUSB3410 
Microcontroller


My
/etc/udev/rules.d/026_ti_usb_3410.rules:

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'"


Driver ti_usb_3410_5052 is requesting firmware ti_usb-3410.bin, which is not 
installed.


linux-image-2.6.27-7-generic installs the firmware here:
"/lib/firmware/2.6.27-7-generic/ti_3410.fw"

cp /lib/firmware/2.6.27-7-generic/ti_3410.fw
/lib/firmware/ti_usb-3410.bin

did the trick.
