  AFAIK, Linux serial driver is lacking some facilities needed for ti-usb
driver to work.

  Download the full driver from
ftp://flower.upol.cz/dts/lin0001_ti-usbserial/sources into a local dir.

  To get a standalone build/test place, I've copied bus.c, console.c,
ezusb.c, generic.c and pl2303.h from $(LINUX_SRC)/drivers/usb/serial dir.
After than I added this Makefile:

--8<------
obj-$(CONFIG_USB_SERIAL)                        += usbserial.o

usbserial-obj-$(CONFIG_USB_SERIAL_CONSOLE)      += console.o
usbserial-obj-$(CONFIG_USB_EZUSB)               += ezusb.o

usbserial-objs  := usb-serial.o generic.o bus.o $(usbserial-obj-y)

obj-$(CONFIG_USB_SERIAL_TI)                     += ti_usb_3410_5052.o
---->8---------

and to build you need:
  make -C $(LINUX_SRC) M=$(pwd) modules
and
  make -C $(LINUX_SRC) M=$(pwd) modules_install (as root)

  Then modprobe the new ti_usb_3410_5052 after rmmod'ing usbserial and
possibly your current ti_usb_3410_5052 and you'll be done.

  Good luck.
