Hi there all...

I've got the following problem in linux. I have six USB->Serial devices that have six distint serial numbers.

I must make some code in order to interact with all of them. The problem is that everytime i plug in the usb, the ttyUSB are given in a First Plugged First ttyUSB Number Given kind of policy (i invented this).

I want to associate serial number 111111111 with ttyUSB0, 22222222 with ttyUSB1 etc.

In my view i can make this two ways:

1 - Open ttyUSB* and try to get the serial number of this device through the filedescriptor or,

2 - use libusb and try to find the ttyUSB devices that are associated with each serial number of the devices i'm using.

I can't seem to find the linkage between filedescriptor and the associated ttyUSB* nor even through libusb to get the ttyUSB*.

I'm new to Linux.

Any help would be appreciated.
