I've heard reports that for some cheap adapters it is not possible. They
don't bother to set the serial number to something unique and so you can
end up with adapters that report absolutly identically (not just
USB-Serial, but they are in the category that is more likely to be that
cheap)
If the USB device does not provide a unique identifier per device, you are
left with the order that they are plugged in, what bus they are plugged
into, or just a race condition about which one replied first.
It's an unfortunante reality about USB
The unique identifier is there but i can't see when i put the usb device on
OpenWRT. It's there when i put on my Ubuntu Desktop.
I ask because i think there are some functionalities unavailable in OpenWRT.
Ok, that's different. Your full blown Ubuntu Desktop is running udev, and has a
much larger pile of rules for what to do with devices in it. If you look in the
logs (and have them configured to log with enough detail) then you should see
the same data from the kernel.
