(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.
