Problem with usb device

[tassheloff]

Hi

my PV inverter is connected wiith my pogo via a USBSERIAL converter which module is ti_usb_3410_5052 and via a PL2303 converter

Both are loaded at start

llsmod
Module Size Used by
pl2303 17252 0
bootled_module 1472 0
ti_usb_3410_5052 25756 0
usbserial 35352 2 ti_usb_3410_5052,pl2303
gmac 40012 0
rt3390sta 893736 1
mii 6200 1 gmac

but the ttyUSB is created only for the PL2303.

If I disconnect and reconnect ti_usb the ttyUSB appears.

How i can have the ttyUSB at startup?
