Yes it worked with 7.04 and 7.10 but not with 8.04 or 8.10.

So if the phones don't have their own drivers where does it get
uploaded from - was thinking that this is kind of built into the
kernal.
Strangely this device works on PCLinuxOS with kernal

Subsequent to your mail did the following (on Ubuntu 9.04)

~$ cat /proc/bus/usb/ > /tmp/usb-before
cat: /proc/bus/usb/: Is a directory


Seems like there is nothing in the above directory
 as seen below
$ ls  /proc/bus/usb/
~$ (returned a blank)

so am posting the output of dmesg - as follows

$ dmesg > /tmp/usb-before_dmesg
$ dmesg > /tmp/usb-after_dmesg
$ diff /tmp/usb-before /tmp/usb-after_dmesg > /home/ram/Desktop/diff_dmesg.txt

This last  output  is selectively copied and pasted below is with ref
to the device ( am not sure if you want the whole dmesg)
