Hi!
I have 3 usb devices connected to my PC. All of them are identical.
Lets call them device1, device2 and device3
They are beeing detected as ttyUSB0 (device1), ttyUSB1(device2) and
ttyUSB2(device3), which is exactly what I want.
The only problem is that when I restart, they often get mixed, and detected
ttyUSB0(device2), ttyUSB1(device3) and ttyUSB2(device1) or any other order.
I can't create rules for these device from serialnumber, or other details
other than usb-connection port.
This is what I get from udevinfo, hoping that someone can help me create a
rule, for all 3.
