USB: oti6858 usb-serial driver (in Nokia CA-42 cable)

Last week I've been searching for a driver for the CA-42 cable (see usb
 below) that fitted my kernel 2.6.20. I only found an abandoned version for a
 driver on your website that indeed worked on 2.6.18 but wouldn't even
 compile with a more recent 2.6.20 kernel.

I fiddled 2 evenings with the kernel code and have patched it up now to work
with the modifications in the 2.6.20 kernel. The patch is attached hereafter
and it works fine (at least for me :-) ).

Bus 2 Device 13: ID 0ea0:6858 Ours Technology, Inc.

I had to fiddle a little with the settings in .gnokiirc but that also
 occurred with the older 2.6.18 kernel. Nevertheless, on one system with this
 cable and my Nokia 6070 I had best results with :

model = 6510
connection = dku5

while on an other system with the same kernel, cable and phone it only worked
with :

model = AT
connection = serial
serial_write_usleep = 1
