Hello,

After two days of searching the net, I finally found the fix we've been
waiting for.
First, I made fetched ti_usb_3410_5052 v1.1 driver, hoping that would fix
it (v0.9 is in the latest kernel for some reason.) After an hour of fixing
it to compile with my ubuntu kernel, I was back to square one with this
error (v1.1 just adds some product ids, doesn't seem to add any other
functionality.)

That was the original error. Essentially, it is a bug in driver. After
looking at 5+ patches, I ran across one by Oleg V.

It is also right here.

So all you have to do, is download your kernel sources, and apply this
patch. Now if yoti_usb_3410_5052ur kernel version is < 2.6.16 or so, you
will also have to add in the PRODUCT_ids for the Ez430 device. I suggest
you upgrade your kernel, since the product id fix is in kernels >~ 2.6.16 or
so.

I applied the patch by hand, to the
/usr/src/linux-source---/drivers/usb/serial/ti_usb_3410_5052.c file.

recompile.... And viola, it works! if I modprobe it before or after the
device is inserted, no hotplug script needed!
Here is the working dmesg dump

[464241.468000] ti_usb_3410_5052 3-4:2.0: TI USB 3410 1 port adapter
converter detected
[464241.468000] usb 3-4: TI USB 3410 1 port adapter converter now attached
to ttyUSB0
So in conclusion, apply patch to a newer kernel, and enjoy. I'm glad I
devoted my time into fixing this stupid problem once and for all.
