Comment 13 for bug 231276

I can confirm that this solution (which is essentially the same as what xorduna posted above) does work for me. I'm using the 2.6.27-9-generic kernel. All I had to do is copy the firmware file to the location expected by the driver and rename it. The link posted by Anshuman gives slightly incorrect file names which may be the reason this doesn't work on all kernel versions, but it's easy enough to find the firmware image, and the expected file name is given in the dmesg output.

For me, I copied /lib/firmware/2.6.27-9-generic/ti_3410.fw to /lib/firmware/ti_usb-3410.bin

This worked well enough for the /dev/ttyUSB0 file to be created when the emulator was plugged in. I haven't actually tested the proper functioning of the emulator yet (I'm not really working with it these days), but expect it should work.

Incidentally, I don't really think this bug should be closed. This is a useful temporary work around, not a fix. The driver should be modified so that it looks for the correct firmware image name. These devices should just work when plugged in, it shouldn't really be necessary to copy files around like this.

Thanks,
Steve
