Problem with iuu_phoenix module

Hi all,
I have just update my kernel to the last available, and I have some troubles
with the iuu_phoenix.c usb module. (update was from 2.6.22 to 2.6.29.2).
The problem seems to come at close(). I mean, when I do a close() of the
ttyUSBx device, the driver not only do the close(), but it's like that we
insert a new physical device.
For example, I have /dev/ttyUSB0. I have one programm successfully using it.
When this program close the device, a new one is coming up (/dev/ttyUSB1 if I
have no other ttyUSB devices). Then, the "old" ttyUSB0 disaspear. This cause
troubles, because at each close(), the device change.
Is this a "feature", or a bug ?
Is this related to iuu_phoenix only, or to the USB system ?
Before, I was using the iuu_phoenix version 0.9 from
http://eczema.ecze.com/iuu_phoenix.html and this problem wasn't present.
But it's no more compatible with the kernel since 2.6.25 (or 26), due to the
changes in the USB structures. I have make a port of the changes done since the
0.5 (which was the base used for the kernel version) to 0.9, and the same
problem exists. If the list is interested, I will be happy to send my patch.
TIA for any help.
Have a nice day.
Olivier
